I'm kind of in the same boat... but it's my own damn fault :-) Our system has grown cruftily over the years (I demo a prototype of a cool new feature, but then it gets rushed into production without proper integration).

I'm slowly converting to the "common library" theme... but it's a real pain. It will be worth it, though (or so I keep telling myself).

I'm actually going with a few libraries. The "common" common stuff that everything needs, and separate libs that distinct groups need.

Update:Changed dorky title to something relevant.
