i've worked with some long tape loops (although not that long) on an old 
copicat tape delay - we set them up with a series of small guiding 
rollers/bobbins on a sheet of plywood, so that the tape loop zig-zagged back 
and forth (like a sort of pulley system).  each bend of the loop requires 2 
rollers, one for the outgoing point of the loop and one for the incoming, 
and the loop is angled around the roller.  hard to explain without a 
diagram, but maybe you get the idea.  as long as the rollers are well oiled 
and your drive motor is powerful enough to pull that length of tape, you 
should be able to set up a similar system over a larger space  (a wall, 
say).

if that really doesn't make any sense (and i suspect it doesn't), let me 
know, and i'll see if i can work out some kind of diagram for you...
