[PHANI] The name-transparency and subscriptions were features that
proved to be very useful. More so because they come bundled along with
the same transport medium that understands those names etc.

[PHANI] The following things come to my mind:

- A recent suggestion by Randy McLeod (mail titled "tipc and routing").
It could be useful to be able to instruct TIPC to use a specific link
for certain kind of traffic.  

- Perhaps a "pure-connectionless" mode of TIPC traffic may be useful.
The connection-less mode that TIPC supports right now still seems to
undergo a "connection-like" treatment at inter-node level. That can
introduce latency and unnecessary retransmissions. Additionally,
send-operations could get blocked (for a max. of link-tolerance
duration) if blocking sockets are used or we end up getting EAGAIN more
often than actually required. A "pure-connectionless" mode could help in
providing a "best-effort" service with "low-latency".

[PHANI] Not so far. TIPC has primarily been used to fit into Opensaf's
MDS requirements and therefore, I would say, TIPC is not fully utilized
by MDS yet. Things such as TIPC's multicast feature are yet to be
explored by Opensaf.
