Yes, the problem at the moment is coordination between udev and 
drakconnect and NM.  The present policy is that NM will *not* be the 
default, which is why udev creates the ifcfg files.

NM is designed to assume that it is in charge of all interfaces. The 
only concession to coexistence with ifplugd is that if an ifcfg exists 
*and* it has NM_CONTROLLED=NO, then NM will not try to control the 
interface.  Conversely, if ifplugd finds that an ifcfg exists *and* it 
has NM_CONTROLLED=YES, then it will ignore it.

For total coordination between all of these, udev, drakconnect, and 
ifplugd would have to look for and check /etc/NetworkManager.conf to 
determine whether NM was active and whether it was paying any attention 
to ifcfg files.  That would determine whether ifplugd would attept to 
control any interfaces at all, and whether drakconnect would even try to 
build ifcfg files for them.
