Just a short note on upcoming conferences: Mashup Camp 3 is happening in two weeks in Cambridge. The attendee list once again looks like a very interesting group and I'm sure there will be plenty of good discussions.
And next month is O'Reilly's ETel Conference covering what's new and interesting in web telephony. And it has a few points of intersection with the mashup space such as discussions on using Amazon's EC2 to run VoIP. Early registration closes next week and O'Reilly is offering readers here a 10% discount using the code "etel07bgd".
