OData consumable in Excel 2007
By looking at the condition of the global economy, I believe there'll be some resistance to upgrade to Office 2010 when it'll be released. oData works great but it only intended to work on Excel 2010 and not Excel 2007. Can Microsoft make the oData consumable by Excel 2007? This will be HUGE for the LOB applications.

The chances of this happening are slim to none, the answer will be "upgrade". Rather spend your votes somewhere else.
