Here's another that uses the route instead of the address to do
something similar:

ip route | grep kernel | cut -f2 -d'/' | cut -f3 -d' '

How the command works:
	* The ip address command gets your network routing table and
	  passes it to the grep command.
	* The grep command searches for kernel and finds a line of
	  content containing the search term. It passes its findings
	  to the first cut command.
	* The first cut command splits the input at forward
	  slashes and removes all but the second field, which
	  contains data that is space-separated. It passes its result
	  to the next cut command.
	* The next cut command splits the input at spaces and removes
	  all but the third field, which is your iface.

It looks like I like to do two cuts. Ah, well. Either of these will
get the job done and maybe someone will come up with a more elegant
one in the meanwhile.
