Why not cache the indexes rather than build them into the modules?  That is,
when you add an OSIS module to the program (be it sword-based or whatever)
you add an index for the file to your internal database (based, e.g. on
sqlite). This would have a number of advantaes:

1) It would be simple (from a programming perspective) to find a verse in
multiple translations.
2) It would be blazingly fast to search. (sqlite is very, very fast.)
3) It would preserve a one-file download with a simple, XML-based format

What you would do would be, the first time the module was opened, go through
and create the index. On modern hardware, this need not take a terribly long
time.  This could be done in a background thread fairly easily.
