I would love to see the good parts from kwifimanager (the systray look&feel) 
merged into knetworkmanager. Maybe I'll do that myself somewhen. 

Right now, kwifimanager is just barely useable, because it can't initiate 
scans when running as non-root user, and therefore can't discover networks at

I'm not sure where you read that. It can handle WEP and WPA as well as NFS  
remounts and VPN connectivity. Its slowly becoming the tool of choice for 
people who frequently roam between networks.
