Sabeer Bhatia of Hotmail fame has invested in www.instacoll.com . He believes that instant collaboration is the next big thing. Anyways, that got me curious enough. I downloaded an instance and I have to agree that its pretty good. It fits into the Microsoft Office suite of products in the toolbar which means you dont have to leave the productivity applications you are working on to start collborating. It allows one click co-editing of documents,application/screen sharing,IM ,whiteboarding etc., and all this for free !!! They have a heavyweight version for corporates as well and that costs a bit. While there are a lot of web conferencing products out there…This is unlike many other products is P2P.
