A demo of WalkingHotSpot will be made available on the TapRoot web site soon, though the demo will only allow one Wi-Fi connection at a time.  It was not made clear whether or not this limitation would continue with the full version of the software.

Windows Mobile handsets with mobile broadband data access can already act as wireless modems for PCs via USB, and sometimes over a wireless Bluetooth connection, but the process of connecting a PC to a handset for this purpose can be complicated with some units.  The WalkingHotSpot software would simplify the process by mirroring a familiar setup - the wireless Wi-Fi network.

While the service will be compatible with both EV-DO and HSDPA devices, those with EV-DO connections will have at least one limitation: simultaneous use.  If a call comes in during the wireless data session, the connection will be severed in order to accept the call.  The inability to simultaneously manage data and voice connectivity is a limitation of EV-DO rather than the software.  Users with HSDPA devices will not be hindered by this limitation as this technology allows for simultaneous data and voice connections. 

Rather than planning to offer the WalkingHotSpot software directly to end users, TapRoot will seek to offer the software to wireless carriers who could then offer it to their customers for monthly fee.
