Updated my rhythmbox cvs today. DAAP support is working. Other then a small pointer cast error in the daap code, things went pretty smooth. I can share and play shared music within rhythmbox. Now all we need is ipod support to include uploading and podcasting. I also have been looking into airtunes support the last week or so. There is a mono/.net project called JustePort that has limited capabilites that can be used to learn how to do the streaming in rhythmbox.
I now now that one of the first priorities is to update the old rhythmbox website to reflect the new development gaines and future direction of the project. NOt to mention, the site just needs an overhaul.
