There is always a peering policy in place and I am sure you have a few requirements in mind and you will be evaluating costs carefully as well as options thoroughly before making a decision on which SP to go for. I am sure technical teams are flexifle to accomodate some bespoke private peering connections and have defined transit products in place so you can always negotiate your timescales w/ them as well as your technical needs.

BGP communities are all the rage? I don't think this is new concept or
fad. Signaling behaviors as well as informing users of types of routes
have been around for awhile. For example, RFC1998 (Aug 1996) outlines
some of these behaviors with modifying local preference. Even Sprint
was advertising the ability to not advertise or prepend to individual
peers back in 2002
(http://web.archive.org/web/20020607092619/www.sprintlink.net/policy/bgp.html).

How is providing better capabilities for your customers macho? People
have been using these knobs 10 years ago and it worked then (just as
well as it works now).
