Hi Mick, all, What will sniffers like KisMAC do in the presence of multiple ESSID access points (the latest Cisco WAPs, for example, let you configure a single AP with multiple ESSIDs, each having its own VLAN, it's own security params, etc.)? I don't know for sure, but I doubt that they're going to generate unique BSSIDs for each (which would make everything "just work" for stumblers/sniffers, right?), but I could be wrong. BTW, I'm soon going to be in one of these environments (we're upgrading our wireless backbone), so I'll be willing to test/suggest/possibly contribute code... - Brian
