We're trying this, too. Most things look perfectly fine so far but we are having some grief handling zimlets. So far, I am guessing that there is no way to centrally manage them across multiple RDS. It looks like they need to be locally installed with one set per RDS rather than per user.
However, we are having grief deploying them. The users are not going to have rights to deploy them but, when we try to deploy them as the administrator from the command line, we are generating errors. I'll place the details in
Add Flickr Zimlet to keep it in that thread.
Any suggestions? Thanks - John
