Is there a way to share a list across multiple Windows Sharepoint Services Sites? 

I would like to build a list that allows people to enter in information about specific projects related to that site, but I would also like all of this information to roll up to one master list that could be viewed and reported on.

My thought was I would build one list and create multiple views to the list for the different sites.  I would like users to be able to access a view this list through list web parts on each of the sites.  Is that possible to do with little or no programming needed?  Can anyone think of a better way to implement a project roll-up besides sharing a list across sites?

 Reviving this post - has anyone been able to do this with MOSS 2007?

 I have nit met much solution of you post.

However, two approaches come to my mind. 

No.1 Depoly a list on every site, then perform lookup from other lists. Obviously this is a dumb answer!

No.2 SharePoint LIst Collection is a solution which may fit into this situation, I have not used it though.
