Client side javascript fast compression library using LZJB algorithm. (code.google.com)

at what sizes is it getting sensible to compress an answer to the server on the client? Could one use that for file uploads?

Interesting but I have yet to think of a way that I could use this.

This, coupled with the FileAPI, could be used for upload compression.

Am I incorrect in thinking that currently, outside of a Flash uploader, there is no way to compress uploads? That even if the server accepts gzip there is no compression of files sent up?

already working on php implementation http://pastebin.com/9Gn8XwQD to use it on one project
