Collaborate Virtually Work together online with these new services.

Interactive web conferences with desktop sharing have gotten us used to the idea of online collaboration. A newer crop of visual collaboration sites kicks the concept up a few rungs by letting you work closely with your remote employees, partners and customers on projects involving trickier media like video and images.
