Replicating Permissions from Author to Publishers

Question

We have a package that contains nodes under /etc/forms/... and we use this to capture some data from the end user.  To allow the entering of data from the user, there's a node of primaryType rep:ACL at /etc/forms/mysite/rep:policy.  This has a child node of primaryType rep:GrantACE, and some other properties to allow anonymous users to input this data for us to capture.  This all works well in the Author environment.  However, I can't seem to replicate these permission nodes to the Publisher environments.
Is there a way to replicate permissions from Author to Publisher?  All of the other nodes in the package seem to replicate correctly, just not the permissions.  I've tried creating a new package with only those permission nodes in them and installing on the Publisher directly, but I get the error:
This node already exists: /etc/packages
Can anyone explain the correct way of dealing with replicating permissions from the Author to Publishers?
Thanks,

I just had a quick read of the docs for Closed User Groups and I'm not sure they fit the bill of what we're trying to achieve here.  At this stage, we're happy for anonymous users to enter the data on this form.  The documentation states:
Closed User Groups (CUGs) are used to limit access to specific pages that reside within a published internet site. Such pages require the assigned members to login and provide security credentials.
The issue is that we need to give anonymous users rights to this section, but can't seem to 'automate' (ie replicate) this permission from Author to Publishers even though it's clearly included in a package.  I don't want to go down the path of manually setting up permissions on each Publisher if it can be avoided - I'd really like to be able to have it set somewhere and replicate across, as per the rest of the JCR.
Is this possible?
