Bayeux 1.4.5.ii Streaming transports

[GregDThomas]

[Duplicate of Issue 19 from the old code.google.com site - http://code.google.com/p/aspcomet/issues/detail?id=19]

Support for streaming transports has a long discussion at http://code.google.com/p/aspcomet/issues/detail?id=19 that I won't attempt to reproduce here, but I'll raise the issue so that it can be kept track of within this space.
