Hello AlvaroI think you are going to have a problem with this.Shindig afaik 
does not support inter-gadget communication. It seems to have done so at one 
point but it has been deprecated: 
http://code.google.com/apis/gadgets/docs/pubsub.htmlThe developers on the dev 
list [email protected] will know better than I if it will be supported 
again in the future.
You might be able to use the existing rpc call mechanism to do it (I think 
rpc.js) - but you'd have to modify the code. This thread seems to discuss this: 
http://www.devcomments.com/Inter-Gadget-communication-at110633.htmBut all that 
would just be about messaging between gadgets - not a visual drag and drop.
What are you planning to use for the visual drag and drop? I'd use jQuery 
droppable or sortable but these won't work across frames, even, I think, on the 
same domain. 
Are you thinking about a feature on a portal you control?  If so - and you 
aren't looking for a general feature that would work with your gadgets on other 
containers I would, for this case, completely fake it. I.e use 2 divs instead 
of iframes and just do a standard drag and drop between those points. (Google 
uses divs in some cases e.g. for feeds - visually the user can't tell the 
difference).
