Stitch_Surfs writes "Blognation is reporting that the IM client FriendVOX has gone live for Facebook. This is the first time that Facebook users (of which there are now some 32 million) can communicate with one another from directly within the Facebook application. This development, by UK-based Techlightenment, effectively closes the loop for any external applications to be used (or necessary) for communication among Facebook users.'It will be interesting to see how quickly FriendVox is adopted and could it ever replace Twitter by simply using the Facebook status. The other question is what will Facebook do if FriendVox ever became too popular? Would they seek to buy it or replicate it themselves? This is the real dilemma facing all Facebook developers living inside the Facebook walled garden, and recently this happened when a developer showed Facebook their new marketplace application which would run inside of Facebook. Inside of two weeks Facebook had suddenly launched their own marketplace!'"
