Why not just lock the cable into the ethernet socket?  I've done that a 
couple of times, mostly by modifying telephone socket locking covers so 
that they'll work with RJ45 wall sockets.  That's a 15 minute job with a 
sharp knife usually and stops little undergraduate fingers from messing 
with the cables at the wall socket end.  I've used thin cable ties to make 
sure that the cable can't be yanked out of the Ethernet card at PC end on 
occasions as well (although most of the locked sockets are either to stop 
people from using them or for embedded devices where the ethernet cable 
disappears inside a locked, hardened steel case).

With the cost of ethernet cards, cables and wall socket inserts being what 
they are today you could even superglue the cables in place. :-)
