[Mason] how to replace $m->cache_self and $m->cache with memcached

[Dragomir A. <and...@ps...>]

How can I replace the $m->cache_self and $m->cache calls in my mason 
code with memcached calls? Well actually I'd like to replace the 
FileCache cache_class with a Memcached cache_class but I've found 
nothing on it, so I thought it might be easier to replace the mason 
cache calls with memcached calls.
Can this be done?

Thank you,
Andrei Dragomir
