It's interesting that this has come up because I've been thinking along these lines recently. Specifically, I'd like to build a service (probably using RoR) that acts as an aggregator for these webhooks.

Imagine that I sign up as jgrahamc on http://somethingmoved.org/ (that was my idea for the name) and a look at http://somethingmoved.org/jgrahamc would give me a 'twitter' style feed of posts that have been made to me.

Then I'd be able to assign endpoints that I could use for specific services, so suppose I decide to use github I might define http://somethingmoved.org/jgrahamc/github and give that URL to github for the post-receive URL.

On my page I can define how that gets added to my feed (perhaps part of the XML document is extracted and added as a simple line of text, and of course for common services there could be ready made templates of what to do).

If standard service endpoints were done right then you can imagine going to a FedEx tracking page and finding a 'SomethingMoved' button where you are asked to enter just the main part of your URL (e.g. http://somethingmoved.org/jgrahamc) and FedEx could automatically tack on /fedex which would then have a standard handling.

Then I also say that this github message should be passed on to other services (perhaps many, perhaps just RunCodeRun). Clearly I could do some transformation before passing things on. For example, I might pass on to RunCodeRun unchanged, but extract part and pass to Twitter.

Anyone got time to work on hacking this together with me in RoR? (I really need someone who's good with web UI hacking since I'm an application guts kind of guy).
