I've compiled a set of DOCX files for a PB of the Soncino translation and notes to the Babylonian Talmud. (As of Sept. 1, 2014 the main remaining work would be to tag the tractates, chapters and dafs with Babylonian Talmud milestones and any referring datatype links; however, they are all fully marked with headings.) Any corrections are welcome. A macro to include milestones should be pretty easy, but if someone beats me to developing, all the better.
