Well, if you use the standard (public) functions in the sb-bsd-sockets
package, your solution should work portably from SBCL on ECL, because
that uses the same API. The ABCL solution I can do myself as I have it
installed (and researched it a bit last weekend): the conclusion is
that - at least - it's possible.

CLISP - from the review of the documentation - will not support this feature.

Which leaves LispWorks and Scieneer. Scieneer is very much like CMUCL,
so if the latter needs adapting, so does the former (most likely).
LispWorks supports :local-address and :local-port keys - at least as
of 5.0 which I have installed here.

This means that we can have this feature everywhere but on CLISP...
Which sounds enough to implement it [and contact the CLISP authors to
implement it on CLISP too].

That's fine. You already saved me many hours of research, meaning we
now can make sure it gets in.

Thanks a lot for your efforts!

(By the way, I hope you don't mind if I take your patch as a
guideline, not as the final one - especially the SBCL backend is
changed more than I'd like: it could be a 4 line change.)


Once more: thanks a lot!

Bye,

Erik.
