Subjective to purpose and approach
I'd imagine more admin's would have a problem with the fact that you can login to their devices with a 3rd party managed authentication mechanism. That and if someone is allowed to login to their account on a corporate device using Live, will they also be able to choose, at the time of login to switch to the standard "Active Directory" username/password authentication similiar to how you can switch between standard login and picture password? I would probably disable Live authentication completely, and the built in live sync, if I can't login to an account on a corporate owned device using the standard username/password combo for a user when they're using Live authentication with the understanding that if I logged in via the standard Domain method that I'd have to authenticate to Live secondarily to enable Live synchronization. We have to be able to get access to their profile on their computer via their corporate assigned credentials without having to know their private Live account info (some situations with heightened security may prohibit an admin from loggin in but in those situations, I can't imagine that Live authentication would be allowed regardless). If that situation is addressed, I'd be more likely to allow Live auth and Live sync on my tablets. I'd be more inclined to have the user create a corporate Live account, allow the settings to sync and instruct them to enable sharing of their SkyDrive storage areas between the 2 accounts...possibly and probably even with a 3rd account, a corporate live account that we can use to backup their personal corporate docs that may be stored on SkyDrive because hey...you never know if SkyDrive will crash and/or that employee may decide to delete our documents that are stored on their SkyDrive. If Microsoft had a nice solution for integrating Live/SkyDrive with our private onsite "clouds", that'd be nice too...that's probably a feature of 360. Note to self, look into that...
