Moonlight 2 beta 7 (at time of writing) is getting really close to working with SilverGlulxe / SilverFyre! The only issue right now is none of the story text appears… 😉 (could just be a simple font issue).
FYI one of the cool things about SilverGlulxe is its handy “Transcript” option (link at bottom of game). It gives you a transcript of the story so far (including your commands) and lets you send a copy (including XML source) by email. Apparently it’s very useful for story debugging [if you’re an Interactive Fiction writer].
