Here's the scenario
Currently still running a gw 8 / Netware setup
Planning on moving that up to 2012 in a couple of months, but in the
interrum we have a remote site that complains about wan speed.
I'm thinkng of giving them their own local po - have an oes 11 server
sitting local to them. so 2 questions (both while thinking about the
2012 upgarde coming soon as well)

Will I run into any issues with a netware GW system and a linux
secondary PO?

Should I give them a seco0ndary domain as well?

Just trying to get their email to open faster, but we don't want to
use caching mailboxes.
