sharepoint 2010 web part

Dear Friends,
We have a web part in a site collection which (reads some data, runs a logic &) displays a summary.
We need to display the same summary at some other site collection as well.

any idea how it can be done....

Page Viewer is not a option since it displays whole page & not just summary.

Hi!
Data query between sitecollection is not available, so I guess the simplest way to do that is to propagate list data from one sitecollection to another (this can be done using BCS - connect data from one site collection as external lists to another).

Look this discussion:

Hello,
As I can see from your description you are using a custom web part, not one of the OOTB web parts (because of custom calculation logic). Is that right?

If it is a custom web part you can use only it's own properties to connect to the data. If it can't be connected to a list in another site collection you can still use Page Viewer but create a special page for this web part with SharePoint Designer. This page can contains only the web part you want to show without any other elements. And this page you can show in another site collection using Page Viewer.

If it is one of the OOTB web part with some customization like Content Query you can use an RSS abbilities or Lists.svc Web Service to get list data from anywhere. In this case you cancopy your custom logic to another site collection (I hope it XSLT) and connect to the RSS data using RSS Web Part, XML Web Part or SharePoint Designer DataView Web Part.

I hope it will give you some idea.
