[wp-hackers] POSTing a file via wp_remote_post

The DropBox PHP toolkit (https://github.com/benthedesigner/dropbox) is 
already doing that bit for me.

I'm just writing the HTTP consumer. The toolkit calls into my function 
with a URL and a number of POST fields. All I need to do in my function 
is perform the HTTP POST operation.

The toolkit is expecting my consumer to POST all the values it sends, as 
the body. So I can't use the above method, because I'm not just POST-ing 
the file; I'm POST-ing a number of parameters, and the file is one. Curl 
handles this by a special parameter. But I need to be able to stream the 
file as *part* (but not the whole) of a stream, using wp_remote_post... 
I suppose one thing I could do is create a new file, but that'll bring 
me other problems (I'm dealing with potentially huge files in a plugin 
that may be used by people in all kinds of situations).
