"seamlessly connect and re-connect across different types of infrastructures without application downtime or user intervention." <---- This is impossible unless the ISP and the Cellular service provider shared the same IP Addressing scheme.


"Our technology is based on mobile IP, which was defined and standardized by the IETF in 1996 and had been known as a technology for years before that," Bryhni told internetnews.com. "Our technology was developed over the past eight years and is based on standardized and well-known protocols." Birdstep has its own patents relating to roaming in and out of virtual private networks. <--- True this will work but it is so so slow due to very large overhead for each of the packet and if you are talking about VPN, a slight change in the packet will disconnect the VPN connection because of security issue.

I hope this might help.

Peace !!!
