I got an email from the National Science Foundation regarding an interesting technology they used to watch all the surveillance cameras at President Obama's inauguration. According to the press release put out by the NSF, the technology created by VSee allowed law enforcement the ability to look at multiple cameras in real-time--even from police cruisers on a mobile phone network connection!
VSee sells their technology as a videoconferencing/application sharing service for companies, though at $50 per user per month, it's a bit pricey. However, you can be assured the service will work over low-bandwidth connections, is secured with FIPS 140-2 certified 256-bit AES encryption, and will traverse firewalls.
You can try the service with 3 users for free to see how well it works. Of course, without a Mac version, it's unlikely I'll spend a lot of time using it. I will have to see how well it works across the great firewall of Nokia before I become an ex-employee ;)
