Dear Christian,
You may like to try and get in touch with Rick Meyers who develops e-sword a free bible study tool and ask how he got persmission to use many translations in his tool like the ESV and etc. Currently he does not have permission to use the NIV, so you may encounter similar problems there...

Peter
P.S. I find that getting people to read a passage from the bible actually helps people to get into the habit of bringing their bibles with them wherever they go, the Word is our "double edged sword", without it we're quite vulnerable... just a thought.
If you want the KJV in text you can download them here:
