you're right in that gmetad currently just get the name from xml NAME
tag. gmetad doesn't do dns hostname lookups. the problem with dns is
further down stream.

pair of them have tcp port 8649 listening, and one of them has a custom
hosts file or certain knowledge of ip to hostname mapping that differs from

the real problem here is not that data will be lost if the ip/hostname
pair changes. the real problem is that the data forks to two different
places.
gmetad is currently not smart enough to know that a fork occurred. i
don't see a simple way to make it smart.
here's one way...
gmetad saves a d
