Hello:

As the chairs graciously requested and got a meeting slot in Buenos 
Aires, I would like to request DANE ALPS (Alternative Local-Part 
Synthesis) discussion time at IETF 95.

The Internet-Draft was posted back in October:
http://mailarchive.ietf.org/arch/msg/dane/5oV9mDolVS09UoF_ZCQOWAH1f9k

https://tools.ietf.org/html/draft-seantek-dane-alps-00

There has been discussion about local-part and e-mail address 
equivalence issues on other IETF mailing list(s) in the last couple of 
months. The Mail Gods say that only the receiving MTA gets to determine 
whether different local-parts are "equal". "Equal" means "deliver to the 
same mailbox" (a conceptual entity). They are right. The proposed ALPS 
protocol does not change anything about this. To the extent people 
perceive otherwise, it needs to be clarified and cleared up.

But the issue is an important one for storing names--particularly e-mail 
address-based names--in DANE, for S/MIME, PGP, and other future protocols.

I suppose that the presentation and discussion time should include not 
only ALPS, but a review of other approaches (see, e.g., John Levine's 
thread "Encoding local parts in better ways" and associated I-D). It 
should also review some of the most common local-part equivalence 
constructs, i.e.:
differences solely attributable to case
sub-addressing ( + - and = )
return-path randomization etc.
UTF-8 (beyond ASCII range)

Regards,

Sean
