Use compressed data directly - from ZIP files or gzip http response (opens in new tab)

I was hoping for something more like this:

Extracting files from a remote ZIP archive (accessing files stored inside a zip file without downloading the whole zip archive)

http://www.codeproject.com/KB/cs/remotezip.aspx

And would like to see an implementation of a server-side means of generating arbitrary .zip files (just storing, without compression) dynamically... for automatic large download integrity verification. Places like http://put.io could use something like that.

If you know that the input data is ASCII-encoded (or Unicode-encoded and capable of being ASCII-encoded), then using Python's cStringIO package (http://docs.python.org/library/stringio.html) is preferential for the significant speed boost.
