I've uploaded a new control to my [downloads page](Item with ID: '6fafe3bc-c4df-4562-b748-636d6de6912c' was not found!) which will allow you to drag\drop a google wave right onto a page! You can see a sample [here](Item with ID: 'e6d4f3c9-36bd-410b-a3e2-59bd846b7cb0' was not found!).
Things to keep in mind:
- Wave is still in beta, and still comes with a bit of a performance hit with gadgets on the page
- You can't get rid of the fugly google blue without getting rid of the login buttons.
So [click on over](Item with ID: 'e6d4f3c9-36bd-410b-a3e2-59bd846b7cb0' was not found!) and see if you can add things to my wave...I don't know if you can without me adding you to the conversation :)
EDIT
Google wave has been abandoned, so this post is pointless now :)
