I just found a NETTagger from another Bible site and it is possible to use their java script to work on any site (temporarily for that particular session). I just click on the book-mark in Firefox, it runs the script and a given site is working with the NETtagger immediately. (They use the following script: javascript:(function(){var%20d=document.createElement('SCRIPT');d.src='h justttp://labs.bible.org/api/NETBibleTagger/v2/netbibletagger.js';document.body.appendChild(d);%20})() ...)
Would that be possible and allowed to do with the RefTagger? RefTagger is much better and of course it is Logos with all the power of Logos and Biblia.com behind it. 
I have no idea how it could be done, so sorry if my question is undue.
