I would very much like to have this auto-pull from Dropbox folders; it is something for another weekend.

I just posted the source: http://github.com/glenmurphy/dropmocks

Auto-pull, auto-push, etc.

Also, to my phone. When I take a picture on my phone, I want it to sync to a dropbox folder.

Also, with facebook. I want each of my picture galleries to sync with a mock (and, optionally, to a dropbox).

Let's say a mock is synced with both dropbox and facebook. Then adding a file to the folder locally on a machine, it should push to mock, then from mock to facebook.

Bah, instead of running my own app instance, do you mind if I make a Chrome extension on top of it, and you can push the code you like back into the running version?

Meta-question: if a Chrome extension uses significant server-side resources, should one ask the site host first? (legally, I think the answer is "no")
