great, so ... bmp can either:
  1) be treated as a non-BGPSEC speaker (synthesize on the output to
bmp listener)
  2) be updated to include the BGPSEC relevant data in payload

downstream tools using the BMP stream(s) of course would have to be
updated. This doesn't seem like a huge deal though, and certainly is

sure, so it has to know about new bits/pieces, nothing new here. If
you catch larry you might get this change/addition into his
final/final version before rfc-editor cuts the rfc.

sure... once things settle out on the SIDR side, I'm positive we'll
have this discussion in IDR. You seem to be working through the
machinations of 'how do I deploy bgpsec in a network', is that the
case? would you be willing to document/presentation-style (or wiki or
...) the process for this? It seems like something other folks are
going to want to reference/use/discuss as well, so having a few worked
examples would be nice.
