Oh, just an aside, there's this one incentive for expressing/ 
generating your optimization problem in AMPL (and you don't even have  
to own a copy of AMPL):

You can use the solvers on the NEOS server for free. Just upload your  
problem, and it is immediately distributed to several machines for  
computation. The only catch is that there are no guarantees when  
you'll get your solution.

They've just introduced an API to communicate with their XML-RPC  
server, so you use NEOS from within your program.

Scroll to the bottom, and you'll see that the sample client is  
written in Python! ;-)

There's lots of free stuff out there.
