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.
The HttpRangeReader class is able to extract a file from the zip without downloading the whole zip. Thanks to new Blob APIs , extracting data from a zip without compression is quite fast. Then, you just have to use url.createObjectURL to convert the Blob object into a URL.
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.
