I think my question was a bit clumsy, I`m sorry about that! What I meant is that it looks to me as CLYW needs aditional software which the Birdstep Mobile IP client don`t need, beacuse The BMIP can cooperate with existing infrastructure and for example autmaticly switch on and off VPN solution. I may be wrong about this, but is it right that the ASNANP consist of at least three parts: a gateway, server and a client? If, so then this is almost the same solution as Ipunplugged or Netmotion(non mobile ip). It looks like it is a propetary solution which will make it difficult to get acceptance by most of the major players since most of them ( for example Vodafone) are looking towards a open solution which can cooperate with existing infrastructure withouth additional software. Again i might be wrong, but i think you guys should take a look at the netmotion solution, it looks quite similar to me.
