How To Manage Multiple Sites

[ninjasmurf]

I wrote a script tha deploys updates from GitHub,annual is just as easy you just FTP over.

But in update check for core and plugins.

Plugins I always test first its fairly easy to swap on and out also there is a plugin updater plugin

Based on the upgrade process from 3.x to 3.2, all that needs to be done is replace /admin/ folder and index.php. This is something I can script but I'll have to tweak the script if the upgrade process changes.

Has the upgrade process been solidified?

Is there a way to poll each site, to see which upgrades (both core and plugins) are available? And is there a way to deploy specific plugin updates to specific sites?

P.S. This problem isn't new. WordPress users have had the same issues. Services popped up to address this (https://managewp.com/) and multisite functionality addressed it for many.
