Collaborative tools?

Like most theorists I collaborate a lot with remote colleagues¹. Recent technological developments like the telephone have made this much easier, but I am ready to move on to something even more advanced.

I have started to use this Internet thing. For example, I use cvs or subversion on most projects to track and synchronize files (see Suresh’s recent post for an explanation of why). I call people on Skype when the connection is good enough for video, and use a mix of email, IM and Wave² to jot down notes in real time about the conversation.

One thing is missing in my collaborative online life, though, and that is a good white board. Ideally, I would like a live holographic image of my colleagues in my office, together with sound and a remotely controllable marker for my whiteboard. Until I write a paper with the doctor from Star Trek Voyager, I’m willing to settle for something less ambitious: an interactive white board on which several people can simultaneously draw, paste/drop in graphics, and write text and latex equations that get formatted in real time.

There are a few free web services and software packages out there that offer something along these lines:

• Scriblink: this has a lot of what I want but a very clunky interface.
• Imagination^3: better drawing interface, no latex/math support
• Latex plugins for Gaim: adds simple latex support to most IM platforms. No drawing. Also, annoying to install on a Mac since it requires a bunch of other packages to be installed first.
• Jarnal: haven’t tried it yet.

A question for readers, then: what other similar tools are out there? More generally, what software has improved your remote collaborations?

¹ I mean physically remote. Some of them are also emotionally remote, but so far neither the telephone nor the Internet have helped them.

² Although Google’s recent Buzz privacy fiasco made me reconsider using Wave.
