I would like to suggest something with the Multisite Copier. I don't know if this suggestion would be best as an update to the plugin or whether a new separate one.
Anyway, I love the multisite copier, however I would really like to set up a system where, content is continually sent to other blogs in the network based on certain rules. This could be through the implementation of categories. So every post/page in a certain category is automatically sent to another blog based on the rules already set up beforehand. Kind of like the Autoblog plugin, but without RSS involved.
