           Summary: Tubes: have a property indicating whether the tube is
                    peer-to-peer
           Product: Telepathy
           Version: git master
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: enhancement
          Priority: medium
         Component: tp-spec
        AssignedTo: telepathy-bugs at lists.freedesktop.org
        ReportedBy: will.thompson at collabora.co.uk
         QAContact: telepathy-bugs at lists.freedesktop.org


It's great that we have fallbacks to ensure that tubes pretty much always
successfully connect. But some applications may want to know whether or not the
connection is likely to be high-latency and low-bandwidth.

This came up in discussion at the MeeGo Conference with a KDE games hacker I've
woefully forgotten the name of (sorry). Some games—multiplayer Sudoku, for
example—don't really care about latency or bandwidth, but for other games it's
not really worth playing if a fast connection can't be established. So we could
provide a way for the channel request to include { Fast: True } so that the
request fails if a fast tube can't be opened, or something.

Of course applications can do their own connection quality monitoring, but it
would be useful to have a really crude measure that clients can use supplied by
the CM.
