I didn't until a few minutes ago... Sounds like this'll do what's needed. One thing I'm not clear on is if it updates as the OSM data changes?
No, it won't, unless you manually update it. I am working on making an API for developers, where you can create/update map data programmatically, so you will be able to do it in a cron job for example.
Thank you; that'd be cool if it would, but it'd definitely need to be optional... Don't want some rogue edits making your map suddenly look like crap.
There are several instances of Overpass API that keep up to date with the main OSM database (usually seconds or a couple minutes behind).
Of course exported data will be from the time of export.
