We are making a document management system, our users usually should
be concerned with .doc, .xls and so on filetypes. They compress well.
Main goal is to reduce waiting time on submitting the form.
First step is to have the uploads compressed, second step is to
transfer only the differences as subversion does it.

So it won't work with Flash. I already found an open source java
applet which could be extended.
