Very cool, congrats guys! Rosetta Stone does something like this already - in addition to learning the language you can engage in peer-to-peer or peer-to-teacher live instruction through the software. It matches you based on language level, etc. The cool part about the peer-to-peer interaction is that it's with someone equally dedicated to learning the language, since they also bought the software and engaged in a bunch of lessons. Of course, Rosetta charges for this service. What does Verbling offer that Rosetta doesn't - is it easier/faster/cheaper/etc?
