I appreciate the quick responses.
Fortunately the server I run is a very small community, people I know in real life, so it wouldn't be out of the question to have to do a manual install on their clients. Like I mentioned, it's an important aspect of the server, so I'd be up for at least trying.
The only problem is, I'm rather new to hosting Tekkit.. could someone explain how I'd go about re-adding Balkon's?
