Has anyone had a look at Juxta, from UVa's Patacriticism group? http://www.patacriticism.org/juxta/ ; best intro seems to be in the manual http://www.patacriticism.org/juxta/wp-content/uploads/2006/02/JuxtaManua l.pdf (warning: 1meg pdf):
"Juxta is an open-source cross-platform tool for comparing and collating multiple witnesses to a single textual work. The software allows users to set any of the witnesses as the base text, to add or remove witness texts, to switch the base text at will, and to annotate Juxta-revealed comparisons and save the results.
Juxta presents several kinds of analytic visualizations. The most basic collation offers a split frame comparison of a base text with a witness text, along with a display of the digital images from which the base text is derived. Additionally, Juxta has several visualizations for the collation of multiple witnesses. Juxta can display a heat map of the textual variants that allows the user to locate-at the level of any textual unit-all witness variations from the base text. Users can also view the collation as a histogram, which displays the density of all variation from the base text and serves as a useful finding aid for variants in long documents. Finally, Juxta can output a lemmatized schedule (in HTML format) of the textual variants in any set of comparisons."
