I think it would be very nice if InsaneJournal offered support so that journals could be backed up using http://www.ljbook.com/ . LJBook uses the XML files for a journal to create a PDF file containing the journal entries and comments. The site FAQ says it can work with any journal service that uses the Danga engine, provided the site administrators give LJBook permission to do so. Right now, InsaneJournal isn't listed as a supported service (whereas LiveJournal, GreatestJournal, and DeadJournal are).
