Don't?

Why not just do a PUT request with all the data as unmangled binary?

Well, you set it at the web server.. That stops both overlarge content- 
length requests, and when the body exceeds the specified content length.

But yes, you have to provision temp file space for n files in flight x  
max file size...

(I have an HTTP::Body subclass I use to stream stuff directly into  
mogilefs rather than getting a temp file - code on request)...
