Native WebOS z-machine?

I’ve yet to google up a native WebOS z-machine. Does one actually exist, or may be on the horizon? I’ve seen a couple JavaScript ones, but as a veteran Kronos for Palm user, I would prefer a native one. It would simplify loading .z5 files and save/restore.

Isn’t that what Parchment is?

No, webOS is its own thing. I haven’t heard of a z-machine for it though.
