That is irrelavent to the people who need to use it to fit in with
an existing network architecture.  I also hear that many Windows games like
to use IPX because it's faster on a local network, but I don't know
if that is true or not.

True, but no one is trying to do that.  Find a way that a netfilter 
is inherently more efficient than device-per-VLAN and tell us about it.  Or
implement it, I think Jamal is gonna start working on that... 

Remember that linear searching of the device list will be hashed shortly, and 
the truth
is, if you need to search the entire device list, say for TCP/IP routing
information, then you'll have to search all of the VLAN device-let structures
too because they hold routing information.
