Do you use the seemless roaming, compression, encryption or policy based routing in NetMotion as well? Do you have users going from network segment to network segment? NetMotion is incredible for very mobile deployments and tends to mask coverage issues and handoffs. Did you already pay for NetMotion? It is a considerable startup cost if you have, and you should only be paying the yearly maintenance, if that is the case, hold on to it! You will find use for it, even if you don't currently meet the criteria above.
