Well, you can, but it won't work. If you spread a single IP subnet across multiple VLANs (and don't use bridging which as you pointed out defeats the purpose of the VLANs), all ARPing (broadcasts) abilites will cease to function across the VLAN boundaries, and any clients on VLAN 1 (or 2) won't be able to ARP and talk directly to the clients in in the other VLAN, thus effectively "breaking" the TCP/IP subnet from working. You say you can put 2 physical segments in the same logical (IP) network (subnet), but again, without bridging, the clients in one physical network won't be able to broadcast ARP for the MACs of other PCs in the same subnet that are on the other physical segment again, the IP subnet would be "broken" Mike W.

So I would say no since VLAN's are used to > seperate segments. Why do you want to do this anyway? As the topics I discussed about 2 weeks ago here. For security. Suppose that in a big environment, such as campus network. There will be many IP "theft" problems which occurs mostly in the housing networks. One way to stop this IP theft problem is by automatically assigning unregistered MAC address into one VLAN, and the rest in the appropriate VLAN.

Well, you can, just like you can put 2 physical segments in the same logical (IP) network. Of course, the question begs to be asked, "why?" as this doesn't give you anything.
