Non-Standard Use of MPLS

Dear MPLS-Experts,

I am aware that MPLS is intended to be used for switching purposes, but
I was wondering if anyone knows about implementations or plans that
make use of MPLS in a non-standard way, like

- MPLS is still used to make forwarding decisions, but the stack
contains also non-forwarding relevant information either in Exp bits or
in separate labels (type of information possibly identified by Exp
bits)
Or
- The MPLS stack is only used as a "vehicle" to encode additional
non-forwarding relevant information. Forwarding decisions are still
based on the underlying protocol (e.g. IPv4).

When talking about non-forwarding relevant data, I am thinking of
information used for encryption, network statistics, billing, etc ...

If there is anything out there (or maybe planed by IETF or whoever)
that makes use of MPLS-like stacks as described above, I would be happy
to hear about it (URLs, papers, ...).

Thanks and have a nice weekend!

Bob
