DHCP has some issues with this, it's not standardised, and option 252 
vs DNS lookups for WPAD... it's a bit of a mess.

enforcement.

We actually deployed a similar (evolved version) to this in WinGate 7. 
If you install the AV plugin (free trials available for both), download 
a big file and throw it a progress header.  We patched Chromium source 
to get the client working.  It actually works really well.  Certainly 
stops human timeouts.
  
We didn't test it via a bunch of other proxies though.
  
I've an outstanding task to write up the modified protocol (contrary to 
that I-D it uses 103, name=value pairs, and only sends deltas).
