We are setting up a teaching laboratory with 24 Mac IIcx's.  They are
on an ethernet with a central fileserver; the machines themselves 
have a single 1.44M floppy but no hard disk.  The problem we have run
into is that most mac applications seem not to be shareable; once a client
machine runs the application, other machines on the network are prevented 
from launching that application--the application is "busy".  One exception 
to this is Microsoft Word, but it is truly an exception.  Does anyone know
of a general solution to this problem?  We are using Novell network software
at present, but I do not believe that this problem is unique to Novell--rather
it seems to be a feature of appleshare.
