The Trusted Execution Environment (TEEP) WG met twice this week and made great progress getting
consensus on github issues filed against the arch doc and the OTrP-over-HTTP doc.  On the OTrP protocol
doc itself, there was a big discussion about GlobalPlatform and compatibility with another OTrP derivative
work being published by that org even though IETF previously got, and the WG is exercising, non-exclusive
rights to OTrP via the normal I-D rules (there are no patent disclosures).  The consensus was to break
compatibility with the current version of OTrP used to seed the IETF draft, with the proposal on the table
being to call the IETF work OTrPv2.   Finally, there was a discussion about how to use RATS WG work for
attestation in TEEP,  which was the consensus on in principle at the last IETF.  Several integration models
were discussed and there seems to be good options that will continue to be discussed between TEEP and
RATS.
