	Similar, yes.

	You could populate the CD-ROMs with object memory snapshots that, when 
resumed, start servers on 'localhost'. Message-based negotiation still 
happens, it's just that the clients and servers are all on the same 
machine. The CD-ROM object memories could have all the modules you want 
to convey in them.
