Not so different from the bitten model, is it?

Fine by me.

That's a huge advantage.

In that case I think such a plugin could fairly be classified as "not
maintained by Boost." Since we know it would be built to serve Boost's
needs from the ground up, I think it's preferable to go that way than to
try to modify Bitten.

Their loss. However, if you publish this thing on trac-hacks.org, it
*will* gain a user community.

No, let's do this. I've never understood what the big deal about
modifying Bitten is, in part because I think what it does is so damn
simple, so I don't think starting from scratch is particularly hard
