Wave...Google Wave

Eversince Google  talked about Google Wave the entire world is still in a shock.Everywhere on the web there are numerous talks about what could be the potential of this product.
Redefining the EMAIL and integrating it with almost all the services on the web is the greatest achievement of the Wave.
Its Real-time Concept combined with the power of Open source we could only imagine what Waves The Google Wave will send in this world.
The 1hr 20 minutes video was amazing I've seen the video four times and each time I saw it something became more clear.
One of the best things which Google did was to make Wave opensource.Since its open source its true potential can be unleashed and time which would have been required to that will be reduced as well.
The best part in the video was 
1.Wave as a protocol
2.Wave in Real time communication.
