FWIW, I hate this debate, and try hard to stay out of it. But it really bothers me when people spread factually incorrect information, especially when they try to use that as the basis of their arguments for/against one method or the other.

Why are you signing mail that is being sent to people without PGP support in the first place?

* AFAIK, inline gpg has issues with non-ascii characters. 😞 Correct me if I'm
   wrong.

This hasn't been true for almost a decade, assuming that the person using the non-ASCII characters has correctly set up their environment. And FWIW, it's also not true that PGP/MIME will be 100% successful when one of the communicants has not correctly set up their environment.

* Inline-gpg includes a signature for each attachment. This allows third
   parties to count how many files are attached (and their filenames, I
   believe). gpg/mime include one huge blob, so third parties can't tell this
   sort of metadata.

Nothing you wrote in this section is 100% correct. You *can* send one signature per attachment, but you don't have to. You can also bundle the attachment and signature in an archive, or you can bundle a lot of attachments in the same archive, and sign that, or you can bundle all of the attachments and signatures in one archive .... etc.

It's also not true that PGP/MIME protects you from metadata analysis. The messages are not "one big blob," they are actually separated into parts, including the attachments. It's trivial to see how many attachments are in a message just by analyzing the MIME headers, whether the message/attachments are encrypted or not.

In the end, I'd suggest you go with what you prefer on a whim, more than
techinical reasons.

... or, you could use what your correspondents are able to handle, since theoretically that's the point of communication in the first place? :)

hope this helps,

Doug
