[asterisk-users] videoconferencing with asterisk issues

[Tom Poe]

What's the situation with configuring Asterisk to handle 
videoconferencing over a community wireless intranet?  I found a "radio" 
at www.ubnt.com that is called, Nanostation2.  It has a range up to 15 
kilometers, and sells for a mere $80. 

Seems like a really low-cost community wireless network (intranet) that 
doesn't need Internet access could be set up.  The community could then 
use Asterisk for videoconferencing for a community wide garage sale 
"tour" each week.

Any pointers on what would be needed to do this appreciated.
