Of course. And it even may be the burned in hardware address, every 
wireless unit is shipped with.

Hm. Sounds like: Why do we use something which
a) exists,
b) works and
c) is amazingly simple?

This is boring.

Why shouldn´t we invent something new that
a) does not yet exist,
b) perhaps will never work and
c) is hopefully terrible complicated?

BTW: I found Craigs argument one of the most compelling ones.
Particularly in mobile networks, you will  distinguish between 
"micromobility" and "macromobility". Much of actual mobility issues will 
be covered by "micromobilty", i.e. are handled by the mobile network´s 
internal mechanisms and hidden from IP.
