ActiveSupport::Cache vs. others?


We are building and using a new caching gem. We would like to figure out how to make this most friendly and easy for both existing projects and new projects to use. I’m guessing the best way to get used in new projects would be via subclassing the ActiveSupport::Cache::Store class? Is this expected to be the primary way to use a cache going forward?

What about gems that may be widely used in existing projects like cached_fu, memcached, etc. ? Are these expected to be rolled in through ActiveSupport::Cache over time?

If you had to chose one cache interface to speak (e.g. drop-in replacement, small constructor diff only, or config diff only), which one would you suggest? And if only two, which two?
