The Electric Sheep Company has launched WebFlock, which is an “under 100k/year” Flash-based solution for building white-label virtual worlds. ESC will do the hosting and presumably the work of making the world; their first customer is the TV show The L-Word.
Many of the articles and commentary are comparing it to Lively, but the comparison seems wrong to me — Lively is aimed at end users making small spaces, whereas this seems more like it’s up against SmartFoxServer and ElectroServer as a white-label solution. It will fill a nice niche there, given the radically different style of the visuals — the other two seems to lean towards kids’ worlds.
I would expect to see more adult IP (TV shows, movies, businesses) using this sort of platform for their virtual world presence, rather than embedding their presence inside of a single world.
