run Rev app on two networked computers?

[Kurt Kaufman]

A single Windows standalone consisting of a startup application and a 
writeable data stack.
Two Win XP computers on a peer network (Windows Workgroup).
What would happen if both computers tried to run the [single instance 
of the] standalone at the same time?
Or perhaps one of the computers would run a local instance of just the 
startup application which would point to the [remote] writeable data 
stack?
<sound of explosion> ?

Thanks, Kurt
