I cheat by using Wayfinder's &excludeDocs to remove any Resource Group Parents (in the global navigation) leaving these cached.
I then use the personalize package to display nothing if the user is not logged in and a chunk (with an uncached Wayfinder call, straight <li>, or @code, or whatever) of the resources they have access to.
This way I keep the majority of the menu cached and reduce Wayfinder's hits on the database or the weight of it processing the resource map.
