I was working on some radius code to do this.   Bascically allocate
everything out of a big ip pool and keep track of which user each IP was
assigned to last, and if when they re-connected, the IP was still
available, re-assign it to them.

However, I quit working on it when I discovered the following...

This is great and wonderful, EXCEPT the microsoft stack WILL NOT keep a
connection open across multiple "dialin sessions".  This effectively
breaks any desire to be semi-statically allocated.

Microsoft's crappy stack strikes again....
