Fair point, John, and, as I have privately replied to
others, I have no difficulty with server-based
solutions (though I claim no knowledge as to the
state-of-pay of the type of shapefile server you
allude to). My query is more motivated by the idea
that there are lots of olk out there who - while
having existing projects that could feed such a
library - may not have the time, knowhow or
inclination to implement servers
themselves. Neither am I proposing a centralized
repository - distributed is gooood. Either way, is
there an acceptably lo-tech way to lowering the bar to
getting bite-sized chunks of content up there into the
aether?
Cheers
