Autofill Podcasts on an iPod Shuffle

Recently I purchased a device largely for the purpose of listening to Podcasts - an iPod Shuffle. Up until then I'd assumed (always a slightly foolish move) that it'd be a simple matter of getting iTunes to keep me hooked up with the latest episodes of my favourite podcasts.

Downloading them is great. Syncing them to the Shuffle isn't.

Poking around for more information on this - with the vague notion that there must be a solution out there somewhere - I came across this enlightening post by Matt Taylor. Problem solved.
