On the CMUCL development list, Chun Tian is lobbying for implementing this feature in it, so usocket can use it. However, he's meeting some resistance, because people can't envision the use-case - and as a matter of fact, so have I. Could you describe yours to us, so we understand what it is that you're trying to do?
Sure thing. Before I do, I will mention that this is a commonly available in many tools, ssh -b is one example.
The situation I currently have is a machine with two different ethernet ports and two different IP addresses. Each of these IP addresses routes to the Internet through different gateways. I also have two services (call them A and B) on the Internet that I access from this machine.
Nice. And I said this twice on cmucl-imp...
Due to factors beyond my control, service A is only authorized from IP address #1 and service B is only authorized from IP address #2.
Binding to different local addresses lets me access both services from the same application. This is what I am doing now with the LispWorks api.
