I love the rrdcached functionality and all the work you did on it
and I would not want to miss it.
But it also makes me sad to see you angry or unhappy. So if you
feel that it is better for you to run your own show, I am perfectly
ok with you doing a fork of the cache daemon and hooking it up to
librrd. This will give you the freedom to develop it in any
direction you feel is sensible.

sorry ... I just had not comment on this ... from what you wrote it
does sound fine, its just that in my tiny world, all I would need
to setup a sensible system, in line with the rest of your security
model is that as a remote host is sending his updates to a central
host we can be reasonably sure, it is 'our' rrdtool on that other
host, sending the data.
