Hi...we're in the process of specifying a preliminary wiring plan for a new
	building.  The architects have given us a cable-routing scheme 
	utilizing cable trays along hall-way walls.  Their scheme seems
	acceptable to us except for one point:  the cable trays will be mounted
	in an aluminum tray above the hallway lights (they are flourescent,
	I believe).  The question I have is will the fluorescent lights
	cause interference along the data lines?  Is the aluminum tray
	an adequate shield?  The architects have never installed a cable
	routing scheme like this so they can't give us any references.
	We will probably run RS-232 stuff and perhaps twisted pair ethernet
	abd appletalk, and probably others in the cable tray.

Any ideas?
