It sounds like Tab doesn't care about the use case where you want hundreds or thousands of instances without undue memory use, since he's looking to replace technologies that already don't support this. But it doesn't seem like these use cases are fundamentally incompatible.

That way, XBL2 could enable new kinds of applications and reduce memory use of existing applications, rather than just providing convenience and bridging, as Tab seems to envision.

FWIW, I think Tab agrees with you here (right, Tab? :). If you want to
