Ability to download multiple files as a zip

another library option:

It looks like from here:
http://www.w3.org/Protocols/rfc2616/rfc2616-sec4.html#sec4.4
the Content-Length http header field is required, which will be tricky with a streaming zip file. Perhaps there is a way to determine without error how big the zip will be. Perhaps there's a protocol besides http that will work that doesn't require we know the file size prior to sending.

EDIT: nevermind. It looks like the http library will automatically use chunked encoding if the content length is omitted.

unicode filenames are broken according to here:

It should be pretty easy to expand the "Download" context menu option for multi-select to download a zip.

another thing that's broken:

• canceling a download doesn't abort the operation server-side (try downloading /library/)

what api are we going to use for multi-select downloading? The url length limit cautions me away from encoding everything in a download url. We should be able to support downloading selections of thousands of files.

[andrewrk]

it doesn't have to be a GET. a POST is fine.

I theoretically fixed cancelling a download aborting the operation server side. Untested.

Only thing left to do now is multiselect downloading.
