Yeah, latency might be a good choise for the user. Also it would be
nice to be able to say if packet loss is acceptable. For example, I
have heard cases where DTIMs are skipped just to save power in the
expense of loosing some of the broadcast and multicast frames.

In that case U-APSD needs to be considered as well.

This PSM stuff will be challenging...
