I'd suggest that a plan of what is needed/wanted is the first step. How do<br>
we do this? The wiki??? I know you main devs seem to use irc, but I'm not<br>
in the US, so I can't easily contribute via that medium (i.e. tz issues).<br>
<br>
</div>I'd say write up a plan and send it to the list.<br>
<div class="im"><br>
As a first though to be knocked about:<br>
- can we use the multi-introducer developments to manage node clustering?<br>
<br>
</div>I don't see how that helps. What I think is needed is:<br>
<br>
1) Decide if we are going to trust storage nodes to express the<br>
variables that are correlated honestly. I think it's at least near<br>
impossible not to trust them and make progress.<br>
<br>
2) Decide if we are going to have each node express its correlation<br>
state, or put this in the introducer or similar. I vote for per-node<br>
config.<br>
<br>
3) Design a mechanism by which a server node can advertise some<br>
properties to clients, like "location=US/Massachusetts/Cambridge/BBN".<br>
Display this in the WUI, and make it obtainable in the CLI.<br>
<br>
4) Design a first-cut protocol for encoding what we care about into<br>
properties. I sent a zeroth-cut proposal in the previous paragraph :-)<br>
<br>
5) Design a way to take a list of nodes with their location properties<br>
and make the peer selector/balancer spiffier. I think this is replacing<br>
'shares.happy' with a more nuanced claim. Perhaps just have a way for<br>
people to write their own rules and link it in, and we can experiment<br>
for a while. A possible rule is "on at least 4 servers that differ in<br>
city". Or "at least 5 servers, with at least 3 cities, and no 2 of<br>
which share a site". This rapidly gets messy. But it can be<br>
individualized code as long as it's easy to write.<br>
