"Maybe food for thought stateside, how something similar could be
negotiated with the NA space industry ?"

I believe there was an offer some years back from Intelsat to fly an
amateur payload on one of their geostationary satellites, but the
ongoing costs were too high for AMSAT-NA to finance.

Unfortunately, no public corporation in the United States is going to
donate extremely valuable surplus space and power on a geostationary
satellite to the amateur radio community. In a country like Qatar,
things like this may be done as a way of promoting national prestige,
but to do something similar here, we'll have to figure out how to pay
the bills.
