My 55 ideas for Google Wave :{Some are on it's way} :
Go and vote here : You liked any?

1."Alloww grouping in contacts list like Friends,Co-workers,Bots so on. So when i click on Friends all of them in that group must be added to a single wave, so we need not add each of them."

2."Block/Ban/Kick users, sometimes spammers or sometimes from contact list itself!"

3."Ability to drag and drop media from hard-disk to wave"

As the latest firfox came up was were happy to read the below in there site :

"Currently, an entirely new spec is being drafted for file objects and handling within HTML5. It will provide a much more robust interface for accessing content in local files, in addition to extending functionality for file objects within Javascript/DOM. The primary additions include:

* Drag n' drop of local files into a web page.
* Asynchronous file data access via callback methods.
* Sending file objects via XMLHttpRequest.

DB replication/reflection is on the most import process while achieving a distributed system, which helps in the DB synchronization between remote hosts.

The concept is pretty simple :

1.Setting up the Master.

2.Setting up the Slave.

3.Let the Slave receive events from master and update DB.
