I had a similar issue a long time ago. With a little remodeling of the door, 
you can make room for the wire to pass and the door can then still close.
Just make sure you do it without the owner of the building seeing it. 
(Bottom of the door on side of hinge is a common location)

PowerLine is ok for this kind of use. I just have too many items on the wires 
here that can cause interference.

My internet connection is 180Mbit down, 18Mbit up.
Without Gigabit network (including the WAN-port), I can't get use this.

The rootkit also was installed using "make -j". Suddenly slow server is a bit 
of a give-away.
