database on the server side, if you ever wanted to allow registered people
to re-key and re-download things without paying again, if they upgrade to a
new computer later, for instance. Basically, in the end, you'd end up with
something just as secure as the online banking system my bank uses.... And
I know how costly _that_ is to fund, so I can see why there is a place for
commercial Bible software companies. Any commercial Bible software
companies working on online stuff like this? hope hope...
