I have been using some time with CustomPress today and had thought to use it on a multisite install.
This is not really viable however as it requires embedding code in files and changing file/folder permissions. To do this requires higher privileges than are available to site users.
Is it planned to make this plugin fully usable (Plug-n-Play)by site users i.e. that it won't require regular users to mess about with code or permissions?
It is a great plugin but not yet ready for use on a multi-site by regular users on network subsites...
