Yes VLC can buffer it. The resolution is user selected, so it's entirely 
possible to use a 10 meter projector screen if you have a 1gbps connection 
and a *very* fast PC, of course back in the real world your talking more like 
TV resolution at best, with lots of noticable compression (think "youtube" or 
google video that streams in realtime). These days people tend to have lower 
uploads than downloads as well, so it limits things even more.

In theory 1.5Mbps can stream a 700Mb xvid encoded movie in realtime (like your 
typical DVD rips out on the net, and most people consider that *close* to DVD 
quality). As a mental excercise, if you can arrange:
* A PC that can encode to xvid in realtime at around 1000kbps, with 128 MP3 
audio (or similar), that should be very high quality at 512x384 resolution 
(comparable to TV). 
* A connection with 1128kbps upload (with a slight margin for overhead and 
retransmission), so allow 1.5mbps.
* A 1.5mbps download
* A PC fast enough on the recieving end.

Then you would have TV quality streaming in realtime(live). Of course if you 
have a LAN on the recieving end, VLC can then multicast the video to as many 
clients as you want on the local LAN. Again back in the real world the 
fastest (for upload) connection I can buy at a consumer grade where I live 
has a 512kbps upload, so I'm looking at 24kbps audio, and 384kbps video. This 
is about what Youtube supplies on a lot of clips (by my eye).
