Of course, you'd need a proper e-commerce and registration system and
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
ware companies working on online stuff like this? hope hope...
