This could be the case, anyway I was thinking of something more "robust"
and a little bit complex -- as request/response contents -- to prevent
unauthorized revoking requesting to prevent as much as possible DoS but
allowing for a simple revocation method. This could help environments where
legal issues are also covered -- govenment PKIs, Municipalities PKIs,
etc...

This is exactly what CMP specifies. Many vendors already have support for CMP EE initiated certificate revocation. The interoperability of different implementations of CMP certificate revocation (among other things) has been conducted during PKI Forum and ICSA CMP interop testing quite successfully.

The model I've been thinking of is mostly based on a structure very similar
to the model proposed in OCSP. The choosen transport mechanism could be
HTTP -- this could help browsers in adding the functionality and CSP to
implement the service.
