Running VisualWorks headless for use w/ Seaside?

Ok.. My next question has to do with running VisualWorks in some sort of 
headless configuration
for playing around with Seaside via the web gui that it comes with.. I've got a 
Linux server
I use for all of my development needs but don't normally run X on it so I'm not 
sure whether or
not I can really do that without using X11.. Is that really the only stumbling 
block?  I realize
I'll need to install mod-proxy to communicate between Apache and Seaside and 
would have to
tackle that as well, but I think that's the easier issue.. Any comments would 
be greatly
appreciated!
