The easiest way by far is to use the --bind option in mount, but you 
have to be running a 2.4 or greater kernel.

for example if you /home/Common /home/cust1 /home/cust2 ...

then

mount --bind /home/Common /home/cust1/Common
mount --bind /home/Common /home/cust1/Common

the linux mount commands lets you mount a directory as many times as 
you'd like and pretty much wherever you'd like.
