FBReader would "solve" many of the reader requests under Additional Software on the ILiad Software Wishlist. It is just about the only full function e-book reader for Unix, but I think this is in part because it is so good. dotReader is shaping up as a viable alternative, and it is cross platform. I don't know, though, if dotReader will improve on the reading experience provided by FBReader. Some of the initial features of dotReader are on FBReader's "planned for future versions" list (e.g. Bookmarks and Tables). FBReader will probably never support encryption, so dotReader has the inside edge for commercial e-books.
