First, I would download orca 0.27b2, as it is the most stable Orca yet.

That's right.  The only misunderstanding is that orcallator.se does not
generate the RRD files, that is what Orca does.

Different people do pushing differently.  Some people don't do pushing at
all and have the Orca server NFS export a filesystem that is mounted by all
the systems that run orcallator.se.  Those systems write to the NFS mounted
filesystem.

Other people don't trust NFS for security reasons and use rsync or scp, etc
to copy the files as you mention.

Yes, this will be fine.

Rusty gave statistics for his RRD file set.  The output HTML directory for the
example pages at

	http://www.orcaware.com/orca/orca-example/

show statistics for 10 systems and 34844 Kbytes of space.
