Any idea why the lack of audio (besides the voyeury-creep factor audioless video grants)? This will be a perplexing omission for a lot of users who are already familiar with personal video chat apps like Tango/Oovoo/Google+ Hangouts et al.
I believe you are referring to the one-party / all-party telephone recording laws, where in some states all parties to the call must know the call is being recorded. This is not relevant for this software program (unless it is being used to stream audio from a phone call...)
