Roaming and WDS

Thanx for the insight Jun!

I hope my new understanding isn't too oversimplified...If roaming was really 
only about ESSIDs then would it be safe to say that any AP that has support 
for ESSIDs would allow clients to roam from AP to AP? So my clients could 
roam from my netgear AP to my HostAP AP if on the same subnet with the same 
ESSIDs and that's it?

I sure hope it's that simple...
