Actually, my dial-up is connecting to algex which seems to connect with
your network at Mae-East.  It's 12 hops to ogg.bbc.co.uk, 6 to mae-east.

Thanks.  Have sent my info and a traceroute to the BBC.

Is it xmms or ogg that determines when to kill the connection?  I find it
odd that data stops coming over the modem soon after the initial buffer
fills and the sound starts, and that no more data ever arrives.  I'd have
thought that it would try to re-sync and continue playing after losing a
few packets, so I'd get choppy sound if the data rate was a bit too slow.
I seem to get a buffer (128K) full of uninterrupted broadcast, and then
nothing.  I don't understand, is it just that it takes about as long to
fill my buffer as it does for my data to fall far enough behind the
broadcast
that the broadcaster decides to drop me?

It'd be nice if whatever was controlling/monitoring this "drop" process
on my end would
re-connect after being dropped.  I can envision receiving a large
e-mail and having my ogg bandwidth fall enough to be dropped.  It'd
be a hassle to have to manually re-connect each time this happens.
(Xmms gives me no clue what's going on.  It just sits there, silent.)

Just curious (and obviously clueless.)
