LMS on a multihomed Mac (OS X 10.6) - fix server to use WLAN instead of LAN ?

Obviously LMS just takes LAN networking interface as primary interface to setting up and running.

Is it possible to manually set the detection order to WLAN / LAN instead of just using LAN as server interface?

Currently the only way is to enable both NICs and just unplug LAN cable until the LMS is up and running.

Any ideas?
