For the record, I will note that I have made proposals for simple non- 
multipart location conveyance (using the data: URL), but various  
process-related arguments were made as to why we weren't allowed to  
look at that. (I'd prefer even simpler solutions, such as the one  
that XMPP uses, but that's beyond the political correctness limit in  
GEOPRIV.)

I tend to agree that exhortations to developers generally achieve  
little. On the other hand, I'm not sure that belly-aching about  
multipart is all that helpful. After all, most email clients support  
it and there are libraries in various languages to help with  
implementation. Generating multipart bodies is pretty trivial (as  
opposed to parsing them), and that's all embedded devices will  
generally have to do for location conveyance.
