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 :-).

Thanks,
