Two small things to note:
I've been doing some Civicspace hacking, for Northfield.org. We're going to roll out a CS site within about a month or so, and I've been doing some extensive theme modifications. There's only a few changes left and things we be much better for us. :) I also blogged the process that I went through to install the Drupal banner module into Civicspace for various sponsors. The documentation that comes with it is a little behind the times, so this is a nugget out there for the searchers to hit upon.
