Ok, so here's the question you need to answer: Is it vital that the information put in memcache from Service A be available to Service B? If the answer to that is yes, then memcache isn't the solution. By it's nature, there is no guarantee that what gets put into the cache will ever be there to be retrieved. If not having an update get made between the services is important, than memcache isn't right.
