You should probably do that anyway, if you are worried about Venice,  
because Venice is just a video service.

320 megabytes (MB) / hour is 711 Kbps, which is comparable to pretty  
much any high quality video streaming
service. My AmericaFree.TV streaming service offers right now, for  
example, 500 Kbps and 250 Kbps simulcast video
streaming, with trials of 1 Mbps HD, and users consistently pick the  
higher bit rate by a 3:1 to 4:1 margin.
(See for an example of how stable this  
user choice is.)

P2P is a bandwidth sharing mechanism, not a audience generation  
mechanism. As streaming video takes off, it will
use more or less the same amounts of bandwidth, P2P or no, as long as  
the underlying transport is unicast, not multicast, because the  
bandwidth usage is ultimately determined by the audience. (At least  
we offer multicast simulcasts. If you don't like our bandwidth usage,  
enable multicast.)
