Imagine Image Multimedia is now using ooVoo for their web-based wargaming sessions.
From their announcement:
Skype continues to have issues so we have also added ooVoo for online miniatures broadcast games. Anyone who wishes to take part by commanding miniatures on the game table that we broadcast with camcorders (not webcams usually) simply has to join and does NOT have to install oovoo because the webpage hosts the application, which Skype does not do.
Very cool. We will be broadcasting games more frequently now and the maximum number of players will be one until 6 players are funded which should be before fall.
