Or just use sms.chrome.pl and let that logic of least cost routing be  
the problem of the transport.

you want to tune routing, you could use ad-hoc commands to change the  
routing policy for your account or for a specific number.

What I didn't like in the initial solution, is that the routing  
decision is done in the client based on resource names.

We have a bi-directional SMS gateway at SAPO, and we take care of  
that at the server side of things.
