Online web based code (text) editor

Hello there,

Is there any good online web based code (text) editor with syntax highlighting for different languages (C,C++,PHP, etc) and auto-completion .Or, with at least one of that options (better if both)? Seems that the results from gooogle aren't helping me so much.

Thanks

i don't know of any goog ones out there, but i am making one myself.
it should be out by the end of summer.

bespin is out now, but it's kinda lame and slow.
