Half duplex is not an issue. Basically the idea is radio over IP. I don't want to change the fact that we are using radios. For example, on an enterprise level I'm going to be working with a crew to set this up for our Avaya system. It is basically for emergency communications. Say the fire chief is out of town and something major happens. We would like for him to be able to call in and hear and interact with the squad on site via the radio network from the PSTN or even a cell phone. With http://www.twistpair.com/ this is completely possible but that only integrates with Avaya or Cisco Call Manager at this time. Not a problem as we run Avaya on an Enterprise level but I'm looking for free or cheap alternatives.
Another example and more towards what I am looking at. As a RACES (Radio Amateur Civil Emergency Service) member I would like to have a "crash cart" that would allow instant ability for communications on a range of mediums. GSM cards, EVDO, WIFI, and radio communications all from a small box that can be very mobile and run on something like a gel cell batteries. The ability to bridge between the two would be very useful in cases of disperse conditions where every RACES member could be offering communications to victims outside of net repeaters or have another medium to get back into the tactical net rather than having to utilize repeaters out of the range of the net control. We have internet controlled repeaters and utilize VoIP on a lot of them but we are looking for something that can be small, very mobile and offer other services other than just radio communications. And just FYI the ~$200/channel is for the above named software that does just what I'm explaining.

I don't think that would be what you want. If half-duplex is ok then most radio makers (Icom, Motorola, etc.) have complete turn-key solutions. If you want it "cheap" then your will have to "build it yourself". I don't see <$200/channel happening in either case for VHF/UHF. Please share more info and maybe I can help.
