I'm using my own version of Facades in 4 forums. I haven't seen this mod's code, instead I use just three plugins.
One for global_start (overruling config.php data depending on the host I'm being visite from)
One for style fetch (forcing a style depending on the host, redirecting if someone tries to visit a thread or forum that belongs to another host)
One for cache_preordered_forums (hiding subforums not belonging to current domain).
You can see the result at

That's for the basic stuff. I've had to perform little tweaks to add some extra functionality, like forcing the same avatar and signature on every domain (NFS mounting of those folders), disabling vbseo for domains other than the main (I just couldn't make it work and I'm
not installing a nulled to try otherwise) and tinkering with the sitemap plugin to exclude different subforums depending of the host from which it's being ran.
