RPC

I don't see what the problem is with doing simple RPCs ofer the net. 
POST/GET requests with key=value pair responses seems adequate for the 
average function call. Maybe the return of XML makes sense for functions 
that return a lot of and/or complex data. Most functions don't, though. REST 
seems too religious and philosophical. SOAP and even XML-RPC seem over-kill. 
So we're left with screen-scraping. Security seems positively a non-issue 
since we're dealing with exact same things that CGIs do. I don't even really 
follow the other point in the article. What am I missing?
