There's been quite a bit of work on the RPC code in the OS 0.8 -> 0.9 time
frame, and in most situations the rpc file isn't being used anymore.
It took me a while to find out too (so I know how you feel about the lacking
documentation:), the way to make it work now is to emit a bit of javascript
after each iframe and include the #rpctoken in there, ie something like:
<iframe
width="482"
scrolling="no"
height="200"
frameborder="no"
src="http://example.org/gadgets/ifr?etc#rpctoken=1707975397";
class="gadgets-gadget"
name="remote_iframe_14020"
id="remote_iframe_14020">
</iframe>
<script type="text/javascript">
gadgets.rpc.setRelayUrl("remote_iframe_14020",
"http://example.org/gadgets/ifr?etc#rpctoken=1707975397";);
gadgets.rpc.setAuthToken("remote_iframe_14020", "1707975397");
</script>
Example is a generized copy&paste from a random www.partuza.nl profile page
& you can check it's code for the complete iframe generation flow
