I have successfully compiled Duece's JSDoor in linux and gotten his
Javascript Lord conversion to run in Mystic.

There are quite a few doors in Synchronet's source tree and so far I have
only tried, successfully I might add, the JS version of Lord.

If you want to see what it's like, I have it up on the Diskshop (bbs.diskshop.ca) under the Fantasy Doors menu.
