Sure you can.  You can if you give the interface card 2 IP addresses
and have each process only listen to port 80 on one of the IPs.
I don't know how to do this in IIS; but Apache's docs describe
in their "Setting up multiple daemons" daemons section.   I assume
webrick offers similar?  Or are you considering this a different port?

I'd say his easiest alternative is to run Apache on port 80; and
have it proxy some requests to some ruby server (hopefully better
than webrick - maybe mongrel) and proxy other requests to IIS running
on a different port.  And then firewall off the IIS and webrick ports
of course for security reasons.
