I know this is working at least in part. Cus I can see the wave below. What I don't know is if anyone else can see it. Can anyone and everyone view it or only those that have and are logged into Wave or is it restricted to those that are participants in the wave?
Update: It would appear that you need to be logged into your Google Wave account to see the wave here. :( That, obviously, means you need to have a Google Wave account. Sorry.
I'm still unsure at the moment whether you need to be invited into the individual wave itself to see it.
The way I understand it is that this embed method is a bit of a hack using JavaScript provided by embeddy@appspot.com. However, it's a demonstration of what Google intends to implement in full for Google Wave.
I don't have Wave *boohoo* and I don't see it.
I see the standard page that people without Wave see if they visit wave.google.com
*left out in the cold* ;D
I've got a Google Wave a/c, I'm logged in and I can't see the embedded wave either.
Still, it's new technology, still in Alpha testing, so having troubles is to be expected.
