Hi Tim!

    I don't see a real upper limit.  talloc is 2600 lines, but if someone
drops a 100kloc heap of code in I wouldn't be shocked.

    Definitely.  Direct repo access already exists, but simple tools to
check for updates etc would be good.  I think we'll be lead by users & devs.

    Another thing we're punting on.  For the moment, we have a primitive
namespacize tool, but it's really aimed at preventing conflicts between
CCAN modules and other code, not between modules themselves.  Tho there's
no reason it couldn't be tweaked.

Cheers!
Rusty.
