Execute stuff @login if link is up

[Neal Becker <ndbecker2 gmail com>]

I'm using kde on Fedora FC6.  Right now, I start amarok, akregator at login. 
If I'm wireless these start before I get a chance to run knetworkmanager
and bring up the link (because I need to provide password to kwallet for
the wep key).

What I'd like is to only start amarok, akregator, etc:
1) At login IF a link is up or
2) Later, WHEN the link becomes up

Any suggestion?
