BBC iPlayer now supports streaming Flash for Mac and Linux. Absolutely fantastic—it Just Works, you hit the homepage and you can be watching video in seconds. No need to even sign up for an account. I imagine IP ranges are used to block access from outside the UK.

Two-Faced Django. Excellent Django tutorial by Will Larson that shows how to build a polling application with an interface both on the Web and in Facebook. Also touches on unit testing and Ajax using jQuery.

stompserver. I think this is the lightweight message queue I’ve been looking for: written in Ruby and EventMachine, easy to set up (thanks to gems), interoperates perfectly with stomp.py.
