Implementing Connectable Web Parts which allow multiple connections

Question

Hi Guys

I have 5 different Custom Web Parts developed.

I am planning to use Provider-Consumer framework for active communication between the Web parts.

But some of my Web Parts which are consumers should also work as provider for another Web Parts . And provider Web Part should allow multiple connections.

These Web Parts are derived from SharePoint.WebPartPages.WebPart namespace. I am using MOSS version.

Can anyone give me an example of this kind of implementation.

Thanks Carol
