I can certainly imagine that 5 people each running separate copies of the 
app could be performance intensive.

The first thing I'd suggest doing is set up a system to match your 
intended production environment and just try out the app in it. 
Specifically, browser it as a user and hit it with a tool like ab or some 
other crawler to get a feel for its response times under different loads.

If it's fine that way then the problem is your development environment. 
Really, I think you're _much_ better off giving each developer the most 
powerful machine you can afford and having them do their dev work on it. 
Developer time is usually more expensive than hardware, and sharing a 
single machine seems like a way to spend more than you save in the long 
run.
