So you don't see any way of using a JSPWiki 3.0 implementation
*without* JSR-170? I'm rather surprised, really. One of the real
strengths of JSPWiki is that there's a nice, lightweight file
system implementation too. If the entry ramp is a complex database
that'll likely have huge significance on its use. For example, I've
been working on a lightweight wiki for the OLPC XO (kids') laptop.
It runs fine using the file system but could *never* use a complex
database since the whole shebang must fit into memory.

Agreed -- right now neither do I. But we're not necessarily in a
rush either...
