Just a quick post to check out the OBA Sample Application for Kits MSDN page. The kits provide comprehensive guidance on how to integrate Office with SAP and PeopleSoft (and we'll have others in the future). The kits include whitepaper, install guide, technical walkthrough doc, and source code. We announced the latest of the kits (the OBA Sample Application Kit for PeopleSoft) last week at Kurt DelBene's keynote at Collaborate 08.

From this page, you can get to the individual kits.
Check it out! This is awesome stuff, and it is a rarity to find kits that provide guidance against these two very popular LOB Systems (that is PeopleSoft and SAP).
