see http://community.logos.com/forums/t/73752.aspx for write-up - these seem to be good suited for Vyrso, and since Crossway has the eBook-files ready anyway...

N.B. ceterum censeo: given the strong interaction between Crossway and Logos, I still think that Crossway should automatically send over all their ePub files to Logos and have them made into Vyrso books (save commentaries and the ESV)
