You may well be right. On the other hand, the linux folks seem to have come up with something they thought was worthwhile, which to me indicates otherwise. > Anyway, either you're interested in doing option 1 or you're not...if > you are, I'll be happy to support your work and shepherd it into the > tree.

Yeah, it'd be a little bit better coupled, and some people might think that's worth spending a day or two on, but I'm not one of them. Personally, I think a year or two might be a bit optimistic.
