I wondered about this, too.  I can tell you that I use ffmpeg/ffserver 
every week to stream HDV that is sourced by firewire to VLC on an XP 
computer, sent via http to ffserver and then streamed out over http 
again after a 10-ish minute delay.  Instant time shift.  I have not yet 
seen an AV sync problem.

I use the version in ubuntu lucid-bleed, whatever that it.
