As regards fauxde (love that term, by the by), I'd stick to something closer to the stuff in The Precious Tableau: the rough purpose of it is clear without being too similar to anything currently existing in reality -- it doesn't go on about, to use an example, .exe files, which aren't universal now, let alone millenia in the future. The nice thing about The Precious Tableau, I suppose, is that while it's definitely reminiscent of debugging that really shouldn't be displayed during a program's normal operation, the ideas there are easily adaptable, but I imagine you'll be fine as long as you're not, say, throwing lines of C or Perl or whatever wholesale. Big cluster, lots of programming languages, and so on.
It depends what you're after, I guess; Mithfindel's assembly is a lot lower-level and closer to the machine's operation than the stuff in The Precious Tableau, for instance.
