The problem with an S2 downlink is that any of the countries that don't allow amateur transmission on that band could force ASMAT to turn off the downlink when their country is in the satellite's footprint.

OK, so maybe that's the thing I missed?
I don't know how this would work - I can't believe that an authority in one country can have any sort of power over a satellite organisation in another country. What if the satellite organisation refuse? Anyway, could a satellite, even at perigee, cause interference?
International co-ordination is beyond my level of knowledge and experience, but it is an essential part of the planning phase of a satellite project. Have the IARU satellite advisory panel been contacted about Eagle? There is no mention of it on their website - but they do mention a lot of other satellite projects, and their advisory board have some well known and respected members. I can't find any mention of the IARU in Eaglepedia.

is worth a look.
