My suggestion is certainly aimed towards that goal, but tackled with
an iterative approach.

Basically, organization of the libs could not really be any /worse/
than it is now (e.g. I'm constantly checking ggee, hcs, moonlib and
zexy to find various OS and filesystem externals I need), so I'm
basically proposing the same thing you are, but approached as follows:
* Lazy consensus on a directory structure (I think we were already
making very nice progress on that in the "Proposals for object
categories" thread before it went off track : ) )
* Creation of a branch of SVN with the directory structure in place
* Everyone works together to shuffle the many libs into the new structure
* We each claim a domain we'd like to maintain
* And then, finally, the maintainer (with help from consenting
developers where necessary) begin to rewrite the objects in that
category to have a consistent interface.

One of the benefits of this is it will become much clearer what that
common interface should be once many objects of the same type are
collected together.  And I think it will be much more likely for
maintainers to step forward once the libraries are loosely assembled,
since the potential will be so much clearer.

And of course this does not need to be a mandate - if a developer
would rather keep all his/her stuff together, that's fine.  And, there
will always be exceptions like rtc-lib or sigpack that shouldn't
really be split up.

But, on the other side, I'm assuming there are many developers that
would be more than happy to move their code into common categories -
at the very least including myself, João and Cyrille, and only haven't
done so because the structure did not exist.  And personally I'd be
just as willing to adapt the interfaces of my abstractions to a
category-defined standard, but once again, none exists now to adapt

Does that make sense?
