Hi Jim,
Q3 - SSH is important for me and my customers because many services work under a SSH tunnel (or port forwarding) like pop, smtp, mysql, ftp and scp.
See any restritions ?
Q5 - you believe, or you are SURE ? (maybe a little difference, but ...)
Q7 - need more acurate answer. I need setup SSH almost domains/accounts in my future re-seller plan.
Q8 - yep !
Europe/Uk servers - at moment i have some hosting accounts in US hosting servers and im looking for european alternatives. All my customers are europe based companys. I see your are UK, so i jump to the conclusion your company have hosting services in UK. Sorry.
