Telepresence Solutions Gaining Traction In Large Enterprise Space: Lifesize Product Manager Nov 18, 2010 TCMnet | Beecher Tuttle We seem to have interrupted Lifesize inside DOD program sales rep Sean Galligan, left, during an eye exam. But we needed to wire him in via high def video cam to join us and federal VP Paul Cantwell. The Herndon office of the Austin, Texas-based firm is directing the cam into the hands of federal agencies. It recently acquired Mirial, which will push the firm further into video conferencing through mobile devices. Lifesize says its product is one of the few high def video conferencing solutions that uses any network and any device for enterprise communication. Since its '03 launch, the company has attracted NASA, most military branches and the Dept. of Energy.
