There are a few problems with this scenario :

In order to sign the document and be able to (properly) verify it later you need both the public and private keys of the cert. Otherwise, if all they sent you was their public key, then all you would be able to do is sign the document, and only *that* user with the corresponding private key could verify the digital signature.

If the user were to send you both keys that would compromise the security of the cert...unless you encrypted both with *your* public key on the client machine and then decrypted on the server...then their keypair would potentially be "in the wild".

What you will need to do in any case is write your own Digital Signature plug-in...the problem with that is you need Acrobat to sign the document on the server and that is strictly forbidden by the EULA.
