It's a purely unscientific and anecdotal perspective, but here are my picks for most interesting and most needed technologies from Interop this week, plus the most startling stat I heard in my New York City travels.Most interesting technology: Desktop videoconferencing system from Avistar Communications that can be delivered on a hosted or licensed basis, and integrates with major desktop applications such as IM to include a critical presence element. Want to initiate a video call? Connect with your co-worker or partner in IM, and kick things off.

Most desperately needed technology: The list of data loss/data breach incidents grows every week. Now there are claims that the granddaddy of them all, TJX, is twice as large as the company has been reporting, with 94 million affected accounts.

Which leads me to the...

Most startling stat I heard: One New York-based financial services firm loses one laptop per day and five smartphones per day in taxicabs, says John Pironti, chief information risk strategist for the consulting firm Getronics. A common outcome: The cab companies sell off the gear after 30 days. How that's for risky business?
