One thing I'm not clear about is, are there any protocol or
implementation limitations that require only one CA?

I would think I could take my private key and get multiple CA's to
sign it, then present all of those signatures to the client.  Should
one CA be revoked, my certificate would still be signed by one or
more others.

Does this work?  Does anyone do it?
