A shared online code viewing tool with syntax highlighting?

Question

I work with another developer on projects and sometimes we are chatting about them via IM. We can dropbox stuff back and forth, but it would be nice to have like an interactive version of pastie / google docs where we could see the same code and edit it together with syntax highlighting.

I know Cloud9IDE has something like this, but I am looking for a real-simple, realtime (if possible), shared textarea with PHP syntax highlighting. Does that exist?

UPDATE This is what i was looking for: http://collabedit.com/
