I don't even know why it would take that long... I, and I think many others, would love an opt-in, light-weight, "simple collaborative documents" side channel in the gmail interface (with the option to push a document over to the full gdocs interface) should be doable for them as of about yesterday or the month before. Apparently the larger public needs baby steps on this sort of thing, but lots of us don't.
