We are in the process of testing Vernier. I have not tried different subnets yet but am going to try that tomorrow or Monday. I will keep you posted. Feel free to contact me directly with any questions.

We are investigatinbg this route as our architecture standatrds will not accomodate a separate VLAN for wireless that spans multiple buildings. We are are observing is that with Windows operating systems (Including WINCE 2002) prior to WINXP, the BlueSicket device is working as advertised in providing hand-off of auhtneticiated connection from one building switch to the next. However with WINXP, the momentary loss of signal when transiting from APs is enough to cause WINXP to react to a "network media failure", release the IP address and immediately request a new IP address. While this is not an issue where the APs are located on the same subnet and the probability of same IP address use is high, but for APs on different subnets, the same IP address is not returned and the BlueSocket device cannot maintain the tunnel it created to allow the roam. Question is: anybody else seeing this? Anybody trying this technique with Vernier and not having the problem?
