AFP Out Of Date In OS X Lion

All legal testers of Mac OS X Lion are under a NDA and so NetGear probably would prefer not to risk inadvertently breaking the NDA in speaking about it. NetGear tends not to announce major updates before they hit beta testing, one reason being that unexpected delays can lead to disappointment and also that for obvious reasons they don't want to let their competitors know what they are doing and when they're doing it before absolutely necessary.

As 10.7 is not available yet the lack of support for Time Machine from Mac OS X Lion clients isn't an issue at this time. Being on the bleeding edge updating to a new OS ASAP does have its drawbacks. It's best to wait a little while for companies like NetGear to properly test updates that address compatibility issues against a production OS. Waiting also has the benefit that you shouldn't experience any of the major bugs that may be present in a major OS update.

Hopefully it won't be that long after Lion is released before there's an update. Personally I'll probably wait a while to update most of my machines.
