I'm toying with the idea of making a sort of structured wiki system for writing Guild games to get around the problems of having your database implemented in LaTeX and make it easier to have functionality between the typesetting and the runtime interface autosync. TWiki and XWiki (more capable but horrible documentation) both looked like promising bases, but as near as I can tell they don't support form/class inheritance, which I'd really sorta like. (Imagine you had several types of tickets, and they all had the same basic Ticket fields, but SupportTickets had some extra fields or something, and then CustomerSupportTickets had a different default value of urgency...) I could also roll my own with individual files in Subversion or versioned SQL objects, but that seems like a lot of work. *shrug*
Also, I apparently have a thesis with Franz/Jeremy in PDOS. Can't go into too much detail in a public entry, but looks fun.
