What would it take to convert all of the english Wikipedia to MobiPocket format?
I know you can download XML versions of all the Wikipedia pages from here:
http://download.wikimedia.org/
It looks like it would be about 100GBs of data (uncompressed).
Put this on your iRex iLiad or PocketPC and you have your own Hitch Hiker's Guide to the Galaxy!
The only problems I see are:
1. How well does MobiPocket compress? There are no 100GB memory cards yet!
2. Is the searching of a 1.5 million page document feasible for a mobile device?
