Telepathy Salut on Sugar 0.102 on Fedora 20 almost works

Activities shared by Fedora 20 systems do not appear in Network
Neighbourhood on Fedora 18 or Fedora 20 systems.  Buddies appear.
Activities shared by Fedora 18 Sugar 0.98 systems appear.

So this is a failure to announce sharing of activities on Sugar 0.102
on Fedora 20.

tcpdump shows mDNS packets for every operation except when an activity
is shared on Fedora 20.

avahi-browse output is consistent with Network Neighbourhood.

	avahi-browse -t _presence._tcp # for buddies
	avahi-browse -t _clique._udp # for activities

(avahi-daemon needed tweaking to compensate for lack of SO_REUSEPORT
support in 3.5 kernel; change /etc/avahi/avahi-daemon.conf to set

I have tried
but there is no interesting output corresponding to the event.

I have used strace and seen possible D-Bus activity relating to the
event.  sendmsg(11, {msg_name(0)=NULL, msg_iov(2)=[{"l\1\0\1<\0\0\0/\0\0\0\252\0\0\0\1\1o\0?\0\0\0/org/fre"..., 192}, {"+\0\0\0org.freedesktop.Telepathy.Ch"..., 60}], msg_controllen=0, msg_flags=0}, MSG_NOSIGNAL) = 252

I welcome any suggestions for further diagnosing this problem.
