I've been rather busy lately, so I haven't had much time to work on the plugin. I do plan to support the DR800 but it could take a few more weeks. It shouldn't be too hard to port, but some of the interfaces need to be updated.
By the way, I deleted the attachments in this thread because they were for a very old version, with the old installation scripts. If you have a DR1000 and want to download the DjVu plugin, please go here: http://www.mobileread.com/forums/showthread.php?t=73790
