Brooks,
Sounds great but when's it going to appear?  Is it soon enough to negate
the worth of this as an interim solution?

Also, while on this topic I have a nit-pick.  This convention,
"<interface>.<tag>" is pervasive but despite that, there's a lot of
software that chokes on it.  I've seen some shell-based firewall
builders for example that don't like it.

Does your overhaul patch support naming vlan interfaces "vlan<tag>" if
the user desires it?  If not would it be hard to do?  I've patched my
RH Linux based machines locally to do "vlan<tag>" for the
aforementioned reason.
