I'm also looking into compatibility issues on volumes that have been accessed or are accessed in parallel with Netatalk/AFP.

If the remote server supports NTFS Name Streams then that should not be an issue, since NTFS Name Streams support the same size as a file.
If the remote server doesn't support Name Streams then this data is stored in the famous and ugly dot underbar file. Which is handle by OS X.

So I am not sure why this should be an issue. If NTFS Name Streams is support then SMB handles resource forks the same as AFP from the client side.
