Because "my current Internet connection is slow"
It's not current -- it's all the time!
Around 4.53 Mbps d/l and 0.3 to 0.5 Mbps u/l, ping 40-60 because we live in poor South Africa, and use 3G a bit out of town.
I need a program to read .ePub, and three I tried from Google store /shop failed.

I might be dreaming but is there some way to by pass this problem, or wait 5 years for FTTH or get a new government?
Like dump the App/Ext/Add-on (which name?) into a Cache-in-the-Sky, and then dribble it out at my speeds?
(Worst case scenario - just give up! My preference was free 'Bibliovore')
