I am currently visiting a city where I know nobody, and there is an open
source project headquartered here that is relevant to my professional
interests, but that I have no 1-degree or 2-degree (that I know of)
social contacts with.

I'm going to email them with pointers to my relevant publicly disclosed
work, and this is a use case which it would be nice to build
communication systems to support.

The lack of support for this use case is, IMO, one of the major blocking
points for Pond as an email replacement.  (Pond currently doesn't even
support the simpler use case of "Hi Alice, let me introduce Bob, you two
should talk", but at least there is a proposal on the table for
supporting introductions in Pond.)
