I would first look at zapier (as mentioned first by robgolding) and IFFT ( http://ifttt.com/ ), they can help integrate just about every service under the sun... if you want to host your own yahoo pipes clone here are a few:

http://github.com/neyric/pipes2js

Here also is a MEGA-LIST (and i wouldn't be using caps nor the word mega if I didn't mean it) of yahoo pipe replacements.... not my site, not my lists but clearly this guy did his homework (over 200+ options). http://meta-guide.com/integration/alternatives-to-yahoo-pipe...
