I am not even sure if memcached would be the right tool for the task. I actually want to make memcached redundant which according to the faq it is not applicable. So I guess I am going to set a session table in the database and memcache it.
If persistence is important, that is the right approach. We use memcache for sessions at dealnews, but they are not ecommerce related or mission critical information. It's not worth the DB write for us.
