love calibre and have been using it for quite a long time now without a hitch
In our house we have two readers both of which run epubs now i have been given a kindle 1 which i know will not use the epub format and i also know that calibre can convert non protected books to something the kindle can use.

now my question is if i convert books to kindle format which means in the calibre library there will be different versions of the same book will calibre be able to differentiate which version should be sent to which device happens to be attached at any one time
