Disruptive Telephony

I mentioned it previously, but James Duncan Davidson has now put the set of photos he took for O'Reilly up on Flickr.  So if you would like to vicariously experience the conference, check out the set.  I particularly liked this one to the right (click for the larger image).  Just a great use of focus and depth of field.  The person in focus is actually Jay Phillips, developer of Adhearsion, a Ruby framework for building applications on top of Asterisk.
