We use coverity where I work on proprietary code and part of their service is to report, anonymously obviously, the defect count, type and lines of code etc back to coverity if you want to. Via this they can get an idea of the defects found using their tool over a very large code base.

I think most of you are missing the fact that this is running on a debug unit which already has the capability to run unsigned code and code off of hard drives with no restrictions. The USB dongle has nothing to do with that, until this can be show running on a non-debug unit this is very bogus.

Before anyone goes on about how MS will end up running everything with a proprietary protocol that noone else can interoperate with you should ask about Skype itself. You do realise that Skype is simply a propietary hacked version of SIP? We looked at what it does here (since we are in a similar line of business) and it is scary how convoluted they have tried to make it so that nobody else can provide service/equipment that interoperates with them. They are becoming a closed exclusive network that no other provider can operate with. Yes you can go out to the public network but what if you want to call someone on Skype? You have to use Skype. Why should I be forced to use a certain VoIP provider just to call another subscriber on that network? Anyway just my 2c given where I work have looked at a lot of the details of how these work. Also FYI MS messenger uses SIP to do it's VoIP side communication before you ask, i.e. non-proprietary.
