Brian, I'm finding it interesting that no one else seems to be commenting about Mac OS X support, but if there is someone around (Justin, perhaps?), who could do a build for him, that could put an end to the discussion.
I get the strong feeling that he's a Java IDE person and probably doesn't know how to build a native code app. Eventually, it might be nice if subeclipse adopted Harald Wellmann's vision to use the webdav transport, rather than having to have any native code on the client. Wouldn't bother me to see SVN-UP's native code approach deprecated. --- Noel
