I posted a similar question to this on the main Calibre forum yesterday, and dwanthny kindly pointed out that it would be better addressed to the recipes forum, so here goes.

I purchased a Kindle 3 last week and I've configured Calibre to download some RSS feeds and email them to my Kindle via he free.kindle.com address.

But I would prefer each transfer to contain only the posts I've not yet seen, rather than a rolling cycle of the last n days or n posts.

Of course, that requires the datetime of the last retrieved post in each feed to be stored and used as the starting point for the next tranche.

So my question is: can Calibre do this, ie does it have access to persistent storage. If it can, are there any example recipes I could look at (I know .NET languages but not Python)? And if I have to preprocess the feeds myself before Calibre retrieves them, can I still hook into the 'retrieve - convert - email' pipeline using the Calibre command line?

Thanks for any advice.
