It was done but not documented.
Now, it's done and documented (in SVN trunk).
Here is all available options :
/**
* Available options
*
* =====> (array) servers :
* an array of memcached server ; each memcached server is
described by an associative array :
* 'host' => (string) : the name of the memcached server
* 'port' => (int) : the port of the memcached server
* 'persistent' => (bool) : use or not persistent connections to
this memcached server
* 'weight' => (int) : number of buckets to create for this server
which in turn control its
* probability of it being selected. The
probability is relative to the total
* weight of all servers.
* 'timeout' => (int) : value in seconds which will be used for
connecting to the daemon. Think twice
* before changing the default value of 1
second - you can lose all the
* advantages of caching if your connection
is too slow.
* 'retry_interval' => (int) : controls how often a failed server
will be retried, the default value
* is 15 seconds. Setting this
parameter to -1 disables automatic retry.
* 'status' => (bool) : controls if the server should be flagged as online.
*
* =====> (boolean) compression :
* true if you want to use on-the-fly compression
*
* =====> (boolean) compatibility :
* true if you use old memcache server or extension
*
* @var array available options
*/
