You could possibly run multiple clients. I would assume that might work
because the client is the one that sends back its name, and that name
does not have to be the host name. I don't think the client listens,
right (thinking port conflicts).

I would set up virtualhosts.. but while that works fine for server side checks (i.e. websites), I don't think it would work for port status because that information comes from the client and can only match one CLIENT entry server side.

If I want to monitor certain ports for host xyz and other ports for host abc I can tell the software to do this by configuring the server side hobbit-clients.cfg (analysis.cfg in xymon).  These tests could also be for the same ports on different hosts.  Make sure that the changes appear above the DEFAULT stanza in the file.
