Author Topic: How would you share files between two computers without the internet?  (Read 25042 times)

Without getting too technically involved, the problem seems pretty simple.
Once you look at the physical and legal limitations, it plans your path for you.

1. You don't want to use the internet.
2. You want to encrypt your files, which leaves out amateur radio.
3. You don't want to use satellites (and even if you did, it would be cost-prohibitive).

That leaves you with very few options.

1. POTS (Plain Old Telephone Service)
2. Run your own hard wire 500 miles (not practical and cost prohibitive)
3. RF links (many microwave links, practical, but cost prohibitive)
4. Cellular phone direct networking (direct-dial point A to point B) with modem phones.
(I'm not sure this can be done, but it sounds practical.) The encryption would
be done by your cell phone company, one less thing to worry about, but law
enforcement could "listen in" if they obtained a wiretapping warrant.
5. Mailing CDs/DVDs/thumb drives/hard drives back and forth. They now
make an external open-frame device that you can hot plug and hot unplug
serial ATA hard drives into/out of.

I'm probably forgetting something, but I don't think so.

You forgot that one of his requirements is that the system bandwidth be limited only the the computer which means that at a minimum the "network" has to handle 100Mbps. That certainly leaves out dialup.

I love you guys!  Smiley Hams can always dream the impossible without getting in trouble with other hams.

Have you considered creating a private Yahoo! group, open by invitation only? You can store files in a library accessible only to group members. It works, and the price is right. I belong to several special-interest groups, a couple of them public, and one of them is private. The price is right!

Umm. Basically it's encrypted to obscure the information from being read by other people.

Umm. Basically, that makes it a no go for Amateur Radio.

I'm doing some research on the internet and trying to make it faster. I'm trying to make an open network, comparable to the internet with these extra qualities.

There are thousands of people with billions of dollars of backing behind them working towards this very same goal.  Not a snowball's chance in hades of you being to do better.

- Every user could potentially get an unlimited connection
- Every Server/Website could have an unlimited connection to everyone using it!

How much bandwidth would be required to accomplish the above two goals?

- Every server/Website cold have the ability to experience 100% uptime

Even with constant sacrifices to the propagation Gods, this is a HUGE stretch!

- All communications could be completely confidential between the two individuals talking and no one else.

By definition, this is NOT possible to legally implement using Amateur Radio.

- All using the current set of protocols we are currently using (TCP/IP)
- No one could monitor your communications

See above.

- HTML could be made simpler and still maintain it's (complete) functionality

Changing an international standard?  Good luck!

- The Internet could be FREE (No Price)
- While maintaining proper authentication protocols (people would still be able to be traced for illegal stuff)
- The only hardware required would be a MODERN computer (Windows Vista/7, Linix, Apple)

I have a blueprint, but no idea how to make it work. The only thing I can program in is BASIC and as the old saying goes, you can use any programming language for any purpose, but some are a little better prepared to handle the program you want to write. I'm studying Python, but it makes me want to hit my computer with a sledge hammer. Everything requires a function to make it work.

**EDIT: Oh and anyone wishing to help me program this is welcome.

How about some variation of IRLP or echolink??

I wrote a semi long diatribe but decided to summarize it:
Ok... Enough. Stop now.

In reading the thread the issues evolved from "sharing files between two computers 500 miles away" to creating a new Internet with no boundaries and unlimited everything and simplifying HTML.

Hence, Ok... Enough. Stop now.

I just stumbled upon this thread, and quite frankly, my head hurts.

I guess if you could tap into our parallel universe and utilize the gravity wave propagation between the two, controlling the transfer of your information by quantum entanglement and temporarily store the info, your idea would be semi-feasible. I think that the hard part wouldn't be preserving the info, just trying to figure out how to insure the entanglement and the prevention from loss of information once one end of the entanglement has been modified. I'll reference the problem of Schrödinger's cat and let you deduce the implications and applications of this idea.
