use content deployment paths and jobs in MOSS

Are you looking at bringing data  from a different site  collection and showing on another site collection as a weebpart?

For Migrating Lists, in different site  collection, create a .stp file (save list as template)

Too see the content of different site collection list, create a data  view web part pointin the target list (Using Web services, you can do that )

Content Deployment will sych source and destination. (Making it look identical)
I dont think, this will solve sharing  purpose
