Well, I'm tempted to do that but I'm a bit scared it will turn out to be 
a major task -
I mean, being able to remove network interfaces is a pretty useful 
feature so why
hasn't it been implemented?  Or has it really just not been high enough 
priority for
anyone to bother with?

Anyone else who can fill me in on the basic problem with interface 
removal under 4.x?
What is it that doesn't work, what code (files) should I look at if I 
want to try and
fix it?
