using memcached for storing shared sessions #88

I read in the readme file that using the shared memory option for shared sessions adds a lot of complexity to gain some speed. This bothers me a bit and makes me feel that I should not enable this feature.

What if you just used memcached as an option for storing/retrieving shared session data? Would this make things less complex and still allow some speed gains? Or, would the overhead of interacting with memcached be too great to make this feature useless?

Anyway, I'm not a stud user yet as I am just researching, but thought I would make the suggestion.
