I thought I read somewhere in the perl docs that safe suid perl scripts were 
doable.  Anyway, a binary would be easy enough, too.  If you're so bothered by 
it, why not write up a nice little ifconfig wrapper, and I'll distribute it 
instead of my stupid um_ifconfig :-)

I think you're right.

BTW, configuring the device isn't the only permissions problem with the net.  
In order to set up a slip device, you need to get a pty.  I currently use a 
pts device, and on some distros (like Debian) the permissions on /dev/pts 
don't allow random users to do that.  One more reason to go over to an 
ethertap network.
