[wp-hackers] $wpdb cacheing?

[Jacob Santos]

You'll probably want to take a look at WordPress Mu, but if I remember 
correctly, you stated that it doesn't meet your requirements. Perhaps, 
but modifying it might be easier, since its intention is what you want. 
WordPress is meant to be a single blog (CMS) platform. I remember that 
any attempts to make it otherwise has been met with resistance.

It is an interesting problem. I believe I might have seen a couple of 
ways it might be possible. However, since it is not my requirement, I'll 
probably won't investigate any further.

Good luck.
