Embedding Word in .NET app?

Has anybody ever managed to embed word in a .NET application?* Our customer want to be able to view a mailmerge doc created by us in word, but then track whether the user printed it or not.

The only solution we can come up with is to create the document, somehow show it embedded in out app, and then fire off the print through our app (so we can tell it's been printed).

Anybody done anything like this before?*

I found a few shareware ActiveX controls for embedding word viewers, anyone used anything like this?
