This seems to work wonder Mamhoud. Big thanks!!

On this note, do the caching object and plugins still make use of the  
ENABLE_CACHE constant in wp-config.php.
In other words, is checking if the latter is set to true (and as the  
codex page states, that DISABLE_CACHE isn't set either) to know if  
caching is available?
Or can I just check if the caching functions exist (version handling)  
and they'll just fail gracefully (return false) if cache isn't enabled?
What's the best practice?

Viper: The plugin I'm writing is interacting with an external xml/json  
api, so caching greatly enhance the performance regardless of if it's  
file or mem based, since it limits the remote connections.

Again, big thanks. I'm sure this will be useful to some.
