hehe, sounds familiar to me
We have a shared hosting account on godaddy / USA.
So we can attach more than one TLD to this hosting account including webspace + database. If you setup one major DB and have lets say your first site w/ WCF installed on the root (/) of your FTP Dirs, you can consider linking the second TLD to a new subfolder in the root (like /site2). Now you can install any WCF Apllication like the wbb in /site2 using the WCF from (/) but still being able to reach it via a separate TLD
