Yes, I like this concept. Once connected, each person would make
available a dynamic collection of loops, live audio outputs
(which become inputs to others), and the metadata that describes
which of the globally available loops they are using in their own
mix at the time.

Sharing live audio streams does become troublesome, but giving
the option to quantize the latency to a musical time makes a lot

Yes, oggs for active looping is good, but since each person
involved has easy access to the full quality loops they created,
the combined meta-data that makes up a session can be created at
full quality "offline" by doing the file transfers later.

I'm in. I'll be coming at it from more the technical side, but
that's usually a good thing. We should consider designing the
system as a library API, so different apps can integrate the
jamroom. For instance FreeWheeling, SooperLooper, or even Ardour
could all be good environments to create and work in this
context. If not a library, at least a piece of software
completely decoupled from UI, with some network-accessable
interface (OSC, etc).
Of course, extending the concept to midi/osc loops is also wide
open. Bandwidth issues disappear in that case.
