I've been wrestling with a similar one for a while and been mostly held 
up because the Java applet developer has been... less than prompt.

The only way I've been able to successfully upload very large files is 
by performing multiple put requests and on the server-side aggregating 
them into the "real file".  obviously, world will be more difficult if 
you don't have a uniform chunk size or sequential creation of chunks.
