What is the best way to upload a folder to a website?

Question

I need an easy way to allow users to upload multiple files at once (ie I need to allow a user to upload a folder). I do not wish to put the burden of zipping on the user.

If you're avoiding Flash (and presumably Java?) the JS/HTML-only solution still requires single-file inputs, but essentially you attach an onchange event to your input, adding a new input to the DOM whenever a file is selected.
