Here's even more techies from DC, San Francisco, and Maryland at SXSW Interactive (the technology interactive portion of SXSW). Entrepreneurs and business leaders took over the city, schmoozing with emerging tech company leaders as well as larger players showcasing their technologies, says DC-based Cooley biz development head Katherine Ferguson (right, with San Francisco-based YouEye CEO Kyle Henderson).

Katherine says SXSWi sparks ideas and is a forum for learning. Here’s the Brivo Labs delegation from Maryland (tough gig to come to Austin in chilly March), showing off its security management solutions. The firm just rolled out its first market offering OKDoor, an application that uses Google Glass to open doors. The wearer is inside the building and gets an alert that someone wants to gain access. An outdoor camera sends a photo of the person to the Google Glass, who can remotely unlock the door. We assume they got the idea from Star Trek’s Geordi La Forge.
