In this case you don't gain any advantages of the peer-to-peer
distributed transfer.  You only gain the advantage of another method
of server->client that may be easier to use at the client end.

We'd need a server with the space for 100 DVD's worth of data for
DRG's and another 100 for DOQQ's plus space for other types of maps,
professionaly backed-up.  Also need a big pipe 'cuz non-Xastir
people will find it too.

Now:  Imagine the same kind of a setup as you describe but have it
auto-create the torrent files and keep them around, plus post them
on a web site.  As maps get distributed from BIGSERVER over
torrrent, the bandwidth required would go down over time assuming
enough people became seeders.

Of course the reality is the server would become more popular over
time, but the torrents might keep the total bandwidth used more
under control.  Less of an exponential rise anyway.
