Introducing Peter Thatcher

Hello all,

I wanted to drop a note introducing my colleague, Peter Thatcher. Peter has
recently joined my team in Chrome, and will be participating in the
upcoming Second Screen Working/Community Group meeting at TPAC.

Peter has also been a member of the WebRTC working group for some time and
has made many spec contributions

Peter, feel free to make any additional introductory comments :-)

Thanks all,
Mark
