[wp-hackers] Caching in core? (was: Caching in 2.5: anyone has a file-based caching plugin?)

With regards to the database-based caching... it's hardly worth a project.
It would take all of an hour to make and test a db-based caching solution (like that used in vBulletin), and simply adding it to wp-includes/cache.php (for the core) or as an extension to the core-caching feature by sticking it in wp-content/object-cache.php.....

It's already controlled by the presence of DEFINEs in wp-config.php; but it can easily be switched to an admin-center option.

/me mulls it over.

Anyway, all this talk has got me convinced that a line of code is worth a thousand painted pictures; so I'll see what I can draft up real quick.
