Uses for video will surely grow, he predicted. "Everybody in business agrees that face-to-face communication is more efficient than any other means," Buffin said.

David Siles, CTO for Kane County, Ill., said he has recently received requests from law enforcement officials who want to transmit live video and stored video clips over wired and wireless connections. That would allow police at the scene of a crime, for instance, to transmit images to supervisors in remote locations or other first responders arriving at the scene, he said.

"There's strong interest by law enforcement to pull up a video of an incident because the more information you have in those [police] situations, the better," he said. Kane County is also contemplating a mesh wireless network that could be built in two years to help emergency responders by enabling the transmission of video images, he said.

There is also taxpayer interest in having video streams of county board meetings available for play-back on demand, he said. Under those scenarios, bandwidth demand will definitely increase, he said.

Siles has been in his post nearly four years, and has overseen a network transition from two large centralized Cisco Catalyst 6500 switches to 12 Catalyst 3750 switches distributed through 12 buildings under a decentralized architecture. Siles said he would welcome upgrading to Cisco's 3750G Integrated Wireless LAN Controller, which Cisco announced Tuesday.
