The dynamic modem pool approach is nice in a number of ways, but has a 
key downside - there isn't an effect constraint on the upper bound of 
concurrent instances. You can keep starting them until you drag the 
machine to its knees. The same is true for other apps, of course, and 
any meaningful constraint would need to be based on the aggregate load 
they produce.

On the upside, at least one fast modern machine have been seen steadily 
running 500 instances. :-)
