John Murrell at Good Morning Silicon Valley pointed up a project from Emre Sokullu and Richard MacManus of Read/Write Web to compile a list of all the players in the online video space. From sharing to search, commercial downloads to P2P technologies, it’s incomplete but already pretty exhaustive. It’s even got the requisite map of company logos.

They’re specifically looking to flesh out the list. The P2P and Vlogosphere sections, for instance, need a lot of help. I know that I’ve already got it bookmarked as a reference for when I can’t remember the difference between Brightcove and Brightroll, Vongo and VideoEgg. So drop by their comments and get your site or your favorite service listed.
