Re: [Rtg-dt-encap-considerations] draft-rtg-dt-encap-01 & TSV in Dallas

[Spencer Dawkins at IETF <[e-mail]>]

Hi, Erik and David,

I would be fine with David and Gorry bringing this to TSVWG.

I agree that TSVAREA needs to see it if we can work that out, but that can
take a back seat, especially if at least a couple of RTG design team
members can come to TSVWG.

If that happens, David, do you think sending a heads up to the TSVAREA list
would be helpful?

I suppose most folk who would flip out in TSVAREA would be in TSVWG anyway
:-)
