Aww, it sounds like everyone has relatively fond memories of me! It's mutual, in any event!
As I recall, the name 'Dustin' was taken in Moul (I came in very late, at which point it was clear Moul was shutting down), so I used 'ddb174', which was my University ID.
Now that Cyan et.al. aren't quite as clawful, I could also upload&GPL the source for the last version of UAM, from which you might be able to scavenge something for ULM. It's not a problem, so just let me know.
Another project I wrote some time ago, which might be useful, is a proxy webserver written in Java, which runs on the localhost, and serves up files for various official Myst-related web-sites. It includes all the files for TheRivenJournals, RivenElementary(if you remember that one), the Myst4 online game, the Myst5 online game, and a smattering of official sites, like the (original?) Myst web-site that had those great screenshots not available in game. Obviously, distributing those files is quasi-legal (archive.org is in this boat), not unlike the upcoming situation with making Drizzle user-friendly (Drizzle is the name of the Moul->Pots utility). Both involve the duplication of copyrighted material that was made available for free online: a legal grey-area at the moment.
By the way, Ahra Pahts look fantastic! Very beautiful while making due with few polygons! That nexus area works really well, I think.
