Setting up with Hostopia

Has anyone had any luck setting up domain mapping on a Hostopia server? My client has hosted for many years with Blue Genesis, which is a division of Hostopia. They have their own "unique" server setup. I had set up the network with subdirectories, because it is on a shared IP. But now that it comes time to domain map - it seems it is not possible to park a domain, nor is it possible to even get a static IP! Any suggestions?
