Guenter Bartsch emailed me about the work he, Christian Zoellin, and Stefan Holst have done on an Evolution to Kolab2 synchronizer. It's based on Revolution, the Ruby to Evolution binding that Vicent Seguí and I wrote.

This is the first I've heard of Kolab; the screenshots look pretty nice!

This reminds me that I should do a new Revolution release; Vicent and I (mostly Vicent) have added a lot of new stuff to the API, including functions to access the Evolution tasks.
