I've got a branding feature, deployed in multiple site collections, including the master and system master pages.
The goal is that if a power user does some changes to one of these master pages, these changes are propagated throughout all site collections.
I've read some suggestions about using a module to deploy the pages centrally, but that still doesn't meet my requirements because file is unghosted when edited with SPD, and changes are not propagated.
Anyone has any deployment strategy suggestion to cater for this requirement?
