Re: Using HTML5 Channel Messaging with Web Intents to create persistent relations

Hi,

At the moment, this is one of the things that doesn't work in the shim.
 Because the shim uses a lot of hacks to get it working in IE and FF I have
had to limit some functionality.  Most of this is due to the fact that data
signaling is currently done via localStorage events and you can't serialize
a MessagePort to a string.
