Yes, spaces in client and port names are allowed.

Yes, some clients have problems with that (jconvolver comes to mind). Buts its
the clients that need fixing there.

Yes, on the commandline you need to quote the spaces so they count as one
argument. But that is the case for every commandline tool when an argument
with spaces shouldn't be devided in two arguments.
