I'm not sure you understand the concept of the cache. I highly recommend that you do further reading. What you are suggesting is entirely not the typical way of using it.
Although there are many ways to use memcached, by trying to get it to do something it was not designed to do is likely to just end up with frustration. For starters, memcache is NOT designed to be able to cache everything. It is not designed to add more cache servers to the cluster when one gets full. By doing things the way you are implying, you are invalidating the actual useful purpose of memcache which is a DISTRIBUTED HASH TABLE. Memcache IS designed to be run with multiple instances on multiple servers, which the clients splitting up requests predictably over all those servers. Adding an extra server invalidates a good chunk of the data that is already stored... which although not generally a problem, is the opposite of what you seem to be trying to do.
