These are two quite different issues. One is, if I understand correctly, a question about running two indepdendent DSpace instances on a single computer. The other is about how to get multiple DSpaces to act as a single 'virtual server'.
Getting two independent DSpaces to run on a single server might be a little tricky, but is certainly possible. It's largely an issue of keeping the configuration of the two separate, i.e. making sure they're using a different database in PostgreSQL, and a different installation directory. The tricky bit is likely to be setting up Tomcat: Tomcat runs as a single JVM, and I doubt if two Dspaces can run in a single JVM without problems or code modificiations. You might actually need to have two Tomcats running.
Getting multiple DSpaces to act as a single 'virtual server' isn't something we've done directly yet, though it's definitely something we're thinking about a lot. You could build a service like a 'portal' or aggregated search on top of DSpace using the OAI protocol, but this isn't something that DSpace does right now.
