Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.

Simplest solution here is to overbuild.  If you are going to do a
3-node 'full-mesh' then you should consider 10G ethernet (a melanox w/
cables on ebay is about US$20 w/ cables!).  Then you just enable STP
on all the bridges and let it be.  If you are taking 2 hops, that
should still be well over the transfer rates you need for such a small
cluster and STP will eventually work itself out.
