The Callpod Dragon Bluetooth headset already has the ability to create a walkie-talkie hands-free connection with any other Callpod headset, but now it can connect with any headset.

All you have to do is download the 2PLEX software upgrade for your Dragon, install it, and you can hook up with any other Bluetooth headset to have a two-way conversation, or sync up so both of you can have a Skype call (via PC) or regular phone call (on a cellphone) with someone else. The software is $40, but if you have another Bluetooth headset already and don’t want to buy another Callpod Dragon ($100) it’s a decent alternative for BT walkie-talkie. [Dragon]
