I recently downloaded this software http://boinc.berkeley.edu/trac/wiki/VmServer
along with VirtualBox to see what applications It could be used on over packet radio. Another route would use a higher network like AGW, which uses a sound card instead of a TNC. For the time being I'm experimenting with a application with a Linux Networx Evolocity I cluster supercomputer with a fiber optic network. Eventually, soon I'm going to start apply wireless (packet) networking to the system.
