If you will have ASNAP to integrate both worlds...then all you need is to have an interconnection between #1 and #2 and have the ASNAP server verify/authenticate the ASNAP powered phone for roaming between two network and while roaming, the MIP application in the Cellphone will not be distrupted while accessing resources in the Corporate network. As you can see, ASNAP and MIP is dealing with two different things.
