[amfphp] JSON-RPC: opinions wanted

[Patrick M. <pat...@gm...>]

As you're surely aware, amfphp now supports JSON. Now the way JSON is
implemented is not exactly standard, so I was thinking of rewriting
the JSON support in amfphp so that it conforms to the JSON-RPC spec,
available here:

http://json-rpc.org/wd/JSON-RPC-1-1-WD-20060807.html

Now the issue I have is that the JSON-RPC spec states that it is
REQUIRED to support named parameters. To support named parameters, I
need reflection, and that's PHP5 only. Now some people might want to
have JSON support in amfphp in PHP4, so I was thinking of having two
gateways, json.php and jsonrpc.php. I think that might confuse people
however, having two similarly named gateways. What do you guys think?
Should I settle for JSON-RPC support only, requiring PHP5, or JSON-RPC
and straight JSON, leading to confusion, or the current method, which
is non-standard?
