The future of the spreadsheet

I think the improvement of the spreadsheet is more than just maximizing capacity but the value should be focus on data manipulation.

I think that real time stream data (through a protocol such as XMPP or RSS) can provide a real future for the spreadsheet as the information will flow, generate and also recorded on a more foreward thinking way.

History of a streamed cell can in theory add new ways to manage quotes, results and a type of versioning taken from the cell point of view as opposed to the whole document.

The spreadsheet is a powerful interface to work at, because you see all the data in the same screen. I think this will be greatly improved if this data can have more functionality.

Also it should be easy, and logical to the user, so adding a bunch of acronyms for this process can be a terrible showstoper of this functionality.
