Or broadcasted web caching - people who subscribe get daily updates

There also is a new proposed spec for doing FTP using multicasting
(MFTP - multicast FTP) which has been tested using some INTELSAT birds
with good results. MFTP has also the characteristic of reduced
sensitivity to long latency, but also to the bit error rate (BER) which
is also a problem when using satellites.

Sounds good for push media, too --- without multicast, these will kill
international links.
