There is exactly zero problems mixing and matching operating systems and Armory versions. The communication between online and offline computers is done through pure-ASCII files on USB, and I don't think the protocol has changed one bit since Armory was released 2 years ago. So even ancient versions of Armory can be used on the offline computer, with the latest on the online computer. And as long as both OSes read and write ASCII files, there's no problem there either.
This is why it's rarely necessary to upgrade the offline system. ECDSA signing hasn't changed, and BIP 10 hasn't changed (though it will with the new wallets, BIP 32, payment protocol, and multisig!). However, I have added some extra things that help offline signing; like popup warnings when transactions exhibit suspicious patterns, etc. But it's not critical to upgrade it.
The exception is this version I'm about to release: some people may optionally upgrade because they want the fragmented backup features.
