I doubt you know what you`re talking about,since you`re talking about other things than me. BT and other have compressing technologies which are compensating for the extra packet overhead related too VPN tunneling. Theese compressing technologies BT gets from partnership with Israel-company Orsus and swedish company called bytemobile.
Why are you talking about changing standard? I have mentioned that with one single word. The case is that Mipv4 standard are being mad at this date, som Mipv4 related issues are not standard yet and the proposed standard is included patented technology from BT. Since BT have patented this, they`ll get royalties from competitiors which are using this solution and its the proposed standard. In other words BT have patent on some of the proposed standard related too Mobile IPv4 Traversal Across IPsec-based VPN Gateways.
I`ve been talking to severeal industry expert and they are all claiming that BT and others like Ipunplugged have a proper solution and that they are solving a huge problem, but several things are missing including a proper payment solution for cross usage of nets, roaming agreements (how do you solve the payment when using a competing WLAN?) and there are stille to few Wlan-phones.
Today BT are in the market with Laptop and Pda solution, they have been getting som customers and so are other similar companies. BT have a symbian and windows Mobile software ready and in a short while, this will be used on several smartphones. I think CLYW must get a finished product in a short while to have a chance and i doubt they can get a proper product when spending such a small amount of money. I am not sure, but i wouldn`t be surprised if CLYW was a somewhat scam. All agreements so far seem strange when looking av revenue, all delays and the small amount of money spend indicates that something is wrong here. But of course i might be wrong.
But in all fairness there have been a market delay when it comes to the seamless roaming market, several companies have prosponed market solutions and people where expecting things in late 2004, but from what I have heard the early movers are not presenting broad market solutions until late march month, maybe on the large Cebit event. T-Mobile could easily be a first mover in this segment.
