Well. The short the form-like posts are not a problem. The point was to fix 
big posts.

I am not sure it is important, but POST is often misunderstood, it is not like 
copy at all. From an abstract point of view it is a translation. You send 
something to a place and get something else in return.

GET: url -> data
PUT: data -> url
Copy: url -> url
POST: data -> url -> data

In KIO get and put has been implemented like:
GET: url -> stream of data
PUT: stream of data-> url

But POST still required data upfront:
POST: data -> url -> stream of data

The case we are trying to solve is not having data be concrete data, but 
instead a source of data.

So somekind of 
POST: stream of data -> url -> stream of data

Again. I am not sure such a solution is necesary. I just felt it was a 
suggestion that should be made, because it would make the architecture.. Well, 
more pleasing in my mind ;)
