I have a PRS-700; my wife has a PRS-500. Is there some setting for Calibre that would make it send ePub files to my reader, but lrf files to my wife's?

At the moment, it seems that I only get the ePub file if there is no lrf file. But if I nuke the LRF version, there's nothing my wife can read.

May I suggest that a pair of user-configurable lists may be a suitable solution?
One list would be a format preference for moving to the eBook reader -- Calibre would move the most-preferred format if available, then fall back to the next, etc.

The second list could be just a set of check-boxes for supported formats for each kind of hardware. Those check-boxes could even be pre-populated for known ebook hardware. The only reason to make them user settable would be so that users could forbid a particular format (by un-checking it) or add one (if they have new firmware whose format support is not yet reflected in Calibre's defaults).

Does this sound like a good idea?
