That just shows how little I know about it :-).
On the PDA side, everything is in memory of course. I'm not sure if
that is the case with Sword - but it makes sense for sure. I expect I
will want to figure out searching on a background thread so results
start coming up immediately. But it would be cooL to have searching
so fast that it can be interactive - i.e. in iTunes when you start
typing an artist, the list gets updated with each character typed.
Somewhere in between would be quite nice as well :-).
