Perhaps what we can do in order to list all the serialisation formats without looking weird is to explain that what we wish to do is bring them all together. We can list all the serialisation formats for X509 (PEM, ...)
then PGP, then the new JSON format by BrowserID, then the different formats people want to embed them in :
Html5, rdfa, n3 (for writing by hand), rdf/xml for Tim Bray, etc...

Doing this we can explain that all these formats are assertions about a public key it's relation to an agent, and some information about that agent. These can then be signed. So the semantics of these formats that interest us are these few relations.

Then we can show how people could publish each of these formats at the same URL with their mime type using content negotiation. 

I think we could then call this BableFish Identity, in honour of Douglas Adams.

  Of course as we all know this will cause greater and more destructive wars than ever, as each one group discovers that it's syntactic holy cow was just an arbitrary way of encoding a few relations.
