Now I haven't bothered to check any other machines, but my initial
impression is that this is not going to work...
I just checked the hostids on my 2 primary machines on the same local
network. They just seem to be encodings of the machine's IP addresses.
And since both are PC class machines, the addresses look to be
syllable swapped (but not byte swapped).
192.168.6.94 and 192.168.6.106
a8c05e06 and a8c06a06
So, I have to ask, does the machine you tried it on have an IP address?
