sanity check w/r appData

[Gregg Horan]

I'm trying to implement some gadget configuration persistence  
mechanism in our container, and I ~think~ I see how appData works, but  
wanted to get a sanity check.  I was confused where the appId came  
from, but from the samplecontainer, it looks like it's not a server  
generated ID - but UI drive from the samplecontainer.js/ 
generateSecureToken.

My goal is to support different settings for the same gadget that  
appears in multiple containers (or multiple times in the same  
container).  From what I can tell, it looks like as long as I can  
develop a hash/ID on the client side/js to make such a distinction,  
then I'm all set with the appData by feeding it my own ID.   This  
would be outside the gadget (in the container), thus may not be  
supported if I deploy my gadgets to iGoogle - for example - depending  
on their implementation.

I'd appreciate any feedback if I've interpreted that correctly - or if  
there's something I'm missing.

Thanks.
