IMHO the best solution for authenticated caching is CacheTags (http://drupal.org/project/c
achetags), especially Dick Olsen's fork (http://drupal.org/sandb
ox/dixon/1341260) that will hopefully be merged into the main
module. The key change with it is that objects are cached indefinitely
until they're invalidated by the object being changed, e.g. a
node's teaser in a view will be cached until the node is
changed.
