I'll be interested to learn how it goes, Phil.

One problem I have noticed concerns a Calibre conversion to mobi which seems to be needed for Kindles. The mobi winds up at over 200MB but maybe mobi is like that.

But Calibre can't view its own conversion and I've not done well trying to find an Android app to work with it. It does work with dad's Kindle but the svg graphics are shrunk.

The epub version seems ok for appearance using Lithium on my phone (at least allowing for my eyesight...) and on my tablet. I don't have an e reader but would like to try it on mum's Kobi. Unfortunately, she's mislaid that...
