PS Would it be feasible to add a PDF-certificate-signer so that ConTeXt
prompts for a passphrase and produces a signed PDF?  This would be
particularly useful in the letter module but would in fact be welcome
throughout.

I have been using http://portablesigner.sourceforge.net/ to sign finished
PDF files, but it would be neat to have the process integrated in ConTeXt.

Best,
Michael
