You are the control operator of the remote station. The owner/licensee of the station is only renting you the use of the equipment so, he is NOT being compensated for operating the station.
Perhaps you can prevail on the argument that the station owner is not
being compensated for operating the station. However there is a pesky
part of 97.113(a)(3)
ยง97.113 Prohibited transmissions.
(a) No amateur station shall transmit:
(3) Communications in which the station licensee or control operator
has a pecuniary interest, (aka money interest)
I do not particularly see a problem with Ham A allowing Ham B to use a
remote setup when no money exchanges hands but once the currency
begins to shuttle between parties or other potential bartering takes place
then I do see a potential problem.
