I have a need to put a stamp on each page with a signature. Two questions:

1) Is it possible to have multiple signatures in one documents? Wouldn't the second signature cause the first one to invalidate?

2) Can I automate this so that I sign once, and the signature shows up in the appropriate place on each page/stamp?

Thanks

There are certain best practices to follow when setting up documents with multiple signatures. Here is a short list taken from the Digital Signature User Guide.
1. Document author: Form fields can be ordered, named, and associated with behaviors that limit changes in signing workflows.
2. First signer: Use a certification signature for the first signature in a document and set Permitted Changes after Certifying as needed. The specified actions should not result in a warning triangle to appearing on signatures.
3. Signature validators and subsequent signers: View the signed version of the document and look at the signature’s status icon in the Signature’s pane.

For more detail on these best practices check out the Digital Signature User Guide available at:

It is possible to sign multiple documents and the signatures don't invalidate each other.
If you're interested, there's some useful background (non-commercial) information about digital signatures at http://www.arx.com/digital-signatures-faq.php
