Yes, I am serious although it is a niche market. With Church Slavonic, Hittite, Greek, Latin, and Gothic present in Logos and with logical next additions including Old Church Slavonic, Armenian, and Sogdian, isn't it time to be able to access the Proto-Indo-European roots? It would certain help for reading the philology oriented NT/LXX/Vulgate commentaries and for understanding certain grammars.
