I'm looking for a collaborative editor that doesn't suck :) And that at least supports Ruby syntax highlighting. Also, a developer and I will be using this to program, so Google Docs won't work.
In all reality, I just need a collaborative editor that has the concept of a project. Where both users see the folder structure of a project and thus see what the other user has opened and is editing.
Also, it would be ideal that both users have local copies of the data (none of this "You remote into me and don't get to keep the data when we're done" stuff) so that one can actively develop against each other's code.
Truthfully, I've found such an editor: http://www.n-brain.net/una_ide.html#features
But I'd really like to see if there's something else out there that's just killer.
I've tried ECF and Eclipse, and it seems SO promising, but NONE of the Ruby IDE's implement the very simple methods of incorporating ECF document sharing functionality into them.
So, does anyone actively use Collaborative editors? And if so, what's your setup like?
