You MAY find it degrades the overall video quality somewhat, though; unless you have a good video bridge that can do speed/video transcoding. The built-in bridge in the HDX units MAY drop the video quality to the lowest-common-denominator, so adding the PVX would drop the call quality to CIF resolution (something like 352×288) rather than the higher one normally supported by the HDX units.

I believe it’s fairly inexpensive – $200-$400; and works well if you have:
1) Fast/reliable connection. Remember your DSL or cable connection has limited upstream (300-600k)
2) Fast PC. Real-time video processing can be fairly demanding – although there is a patch required
on that software with dual-core pentiums.
3) If running over a VPN connection, you may have to play with network settings, so it runs over the VPN
adapter, rather than using the non-tunnelled connection
