I've moved to Cambridge and now work for BlinkPipe. The company sells a unique and inexpensive video conferencing solution based on a subscription model. I get to work on the application running on their custom hardware which lets you create a video conference that runs in parallel to a regular phone-call - keeping the two streams separate to take advantage of the reliability of a phone call whilst adding the benefit of video. I get to write a lot of C and work under Linux which makes me a very happy coder.
