That! Is! AWESOME!
I read through your listings with much zeal. I saw Arial and Verdana TTF's in the X11 directory... so perhaps new fonts can be added?
What is your unpleasant suspicion?
I wonder if this method can be used to make the Aluratek firmware flashable. Unpack the firmware, fix the failure check, repack the tar and encrypt...
But wait... we don't have the mtd2 with the .passwd for Aluratek, do we? ...
EDIT: I wonder if you can access the Aluratek's block system manually under Linux. The script under reflash_nor in the jetBook seems like it could be done in reverse to extract mtd1 and mtd2... hmm...
