Using Apple ID for more than one server

Hi,

I have several Mac Mini Servers dotted around the world which run mail/web/etc specific to that area. I keep each one seperate (I dont share the Open Directory) - but sync contacts etc. between servers using iCloud - all good - brilliant in fact.

Here is my question, I would like to Apple Push Notification on all the servers using the same one apple ID/email address. Is this possible?

Cheers

Dan
