It should be possible to set the domain as well as the port that
SRU/Z39.50 listens on in koha-conf.xml. So
/etc/koha/sites/libraryA/koha-conf.xml could have this:

<listen id="publicserver" >tcp:example.com:9997</listen>

and /etc/koha/sites/libraryB/koha-conf.xml could have this:

<listen id="publicserver" >tcp:example.org:9997</listen>

(Same port, different domains.)

I am pretty sure I had this working at some point, but I have not
tested it recently, so Your Milage May Vary...

The explain document served by SRU/Z39.50 is completely static! So you
can change your configs as much as you like, and the explain document
will remain the same, for all sites.

I did create "Bug 12836 - Add a script to regenerate Explain files
from configs" to try and fix this:
https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=12836

But it has been stuck in FQA for a while, because I did not think
enough about having it work with default configs, and because I have
not found the time to fix those problems yet.

Hope that helps (a bit)!
