Hi Chris!

It's nice to go through the list of parameters, since it's difficult
to find out the meaning of each parameters.

Just a few questions:

>  http://<SHINDIG>/gadgets/ifr
>  ?synd=<YOURCONTAINERNAME>

Isn't the synd parameter outdated yet? As I see in the php code, the
container parameter supersedes it.

>  &container=<YOURCONTAINERNAME>

>  &viewer=<VIEWER ID>
>  &owner=<OWNER ID>

Is it necessary to pass the viewer and owner id's here? They are
encoded in the token, and I believe that is more secure.

>  &aid=<APPLICATION ID, CAN BE NUMERIC OR GADGET URL>
>  &mid=<MODULE ID (AKA '4TH GADGET ON THIS PAGE')
>  &country=<COUNTRY CODE>
>  &lang=<LANG CODE>
>  *&view=<INSERT VIEW NAME HERE: profile, home, canvas, preview>
>  *&parent=<CONTAINER URL>


>  &up_<FOO>=<BAR>

Are the up_ prefixed parameters free for use?

>  &st=<LONG ENCRYPTED TOKEN>
>  &v=<CACHE BUSTING MD5 OF THE GADGET XML>
>  &url=<URL OF GADGET'S XML FILE>
>  #rpctoken=<RANDOM UNIQUE NUMBER>

I believe it's worth to mention the nocache or the bpc (bypass cache)
parameter, that forces shindig to reload the given gadget. (Sandbox)
container implementers usually will need this.

Because I had some time figuring out the meaning of those values too,
I've dropped your notes to the cwiki:
