I believe Bryan had a working version of his interpreter which played
(some form of) zipped storyfiles, which gave a useable disc-space
saving (particularly for Psion Organisers!). However, the resulting
interpreter was _not_ usable, due to reduction in speed!
Not, of course, that I'm speaking for Bryan in anyway, and I'm
recounting this from memory, so could be wrong in places. However, his
opinion was (I believe) that it wasn't feasible.
