The iLiad's larger size and its programability make it your only option at the moment (but not necessarily a good enough option). I don't have an iLiad, but from what I have read you may be able to use ssh from another computer to enter and change text. One problem is that it would not be immediately displayed on the iLiad, but perhaps having two displays and using the iLiad for reading and the other for editing might work. EMACS (for example) can edit a remote file via ssh. You might ask on the iLiad Developers Corner about ssh-based solutions, or other ways to edit iLiad files with a real keyboard.
