To understand my point of mind:
- Wave looks great.
- Wave is a step-forward

but:
Where is the data be stored?
What is the advantage for Google?
What happens to my email?
What is the price we have to pay?
What modules are "really" open?

if:
Wave is really "open" it´s okay.

Defining the term open:
Every code line must be readable.
The Complete Code must be run on a private server, with no interfaces etc. pointing to a external source, with the user is not in see more control in.

To Boonex:
You´re doing great. The Dolphin 7 needs more improvement - but I´m looking forward to the release.

Thx,
