Well, that is why I prefer a UI digipeater so that Hams
can QSO live via the satellite and not just exchange
files... which they can now do 24/7/365 via other means.

No, that is the beauty of the PACSAT protocol, one 
uplinks files via connected mode, but files are distributed
to everyone in the footprint and they all capture everything
whether they need it or not.  Stations only requests "fills"
on pieces that they missed.  Kinda like an APRS system
for files instead of single one-line data...

Agree.  That's why I made the subject a dual post
to AMSAT also.  But since the APRS-Internet structure
has so many gurus that could easily set up a "side
channel" for ECHO just like they did for the APRS-IS,
I thought I would ask here first...
