> Still lightyears ahead of templates on other CMSs... Yup, but I think that's primarily because WordPress has a stranglehold on the market. Nobody will use another CMS because WordPress has all the stuff, and nobody will develop mass-market stuff for another content management system because WordPress has all the users. The network effect is strong, and displacing WordPress wouldn't be profitable enough to be worth…
I think the best way would be to come up with a way to port those templates to other CMS that doesn't involves rewriting the whole thing, or perhaps a wrapper?
WP templates are so coupled to WP itself, I truly don't think it's worth it.
