The problem with any broadcast technique is acknowledgements. This is
much worse in the satellite case, since cheap satellite receivers and
even most cable companies provide one-way traffic only.

You would need some fairly high redundancy forward-error-correction
to get "acceptable" reliability. Maybe the method which banks have used
for years with fund transfer would help also, namely, to simply get
what you get and ask the sender (central site) to re-broadcast any
sequence numbers you missed.
