I have some experience of remote work, e.g. my current job. Not being in the same room is mostly not a problem at all. But for some reason, trying to do research together remotely is much harder, and several people I have talked to share this experience.

I have some intuitionist about why this is the case, but I also don't expect it to be very useful to discuss the reasons something can not be done. Instead I'm asking for positive examples.

Can you tell me about any successful remote research collaboration? And if so, give me as much information and general context about it as you can.
