[Plugin: W3 Total Cache] install every subdomain in wordpress mu to work?

for WordPress MU, or WordPress 3.0, you can install it and activate it on the network level, you don’t need to install it on every blog.

Settings for each site still need to be configured as not all options support network wide activation.

Is this something that can be added as a Super Admin option, because regular users who sign up on an MU/3.0 and get a blog don’t need to be mucking around with the caching stuff? That should really be a Super Admin thing only, IMO.

For example, you can’t get a WordPress.com blog and expect to configure your own caching/cdn… Automattic does all of that stuff behind the scenes, and it is the default setting for all users. As it should be, since it’s a back-end kinda thing.

Perhaps there could be some core settings that can be added as wp-config variables. The users never see wp-config, but the same file works for every blog, so this would be a perfect place to set those vars without Joe User poking his fingers in the pie. I know one of the WP SMTP plugins uses this method for MU installations…

When you install W3TC on a super admin site those settings are used as the defaults when activated on other sites. Also in the next release settings can be exported / imported to make configuration of similar sites much easier.

WordPress.com is irrelevant. They provide a service and a customized flavor of WP MU for their users. Furthermore, they provide no minification nor page caching to disk, among numerous other nuisances that make your suggestion non-trivial.
