You make good points, Tim.  I have one thing to add, if people aren't
already aware: the change_notifier <http://www.ros.org/wiki/tf#Nodes> node
trades off tf bandwidth for latency and accuracy.  The trade-off is
configurable.  I use it, for example, to reduce the tf bandwidth on a PR2
from a constant hundreds of KBs per second to between zero (static robot)
and a few KB/s (single arm moving.)
