> email subscriptions to RSS for example, or perhaps even the other way around

There's actually quite a few powerful services to do this. I made a service called http://feedsub.com to do this a couple years ago. I'd also recommend http://mailbrew.com which has a nice digest format.

I think there's a lot of value in RSS as an underlying data layer for the web, and I think it's criminally underused on the consumption side nowadays.

For example, I'd very much like to see blogrings make a comeback, and there's probably room for a website community driven entirely by mailing lists and one of these RSS-to-email tools.
