To solve the admin beaming issue, just give it a jumpdrive. The FLHook code is there and it does work perfectly. Some people have raised concerns over lag when lots of people use it but I've yet to see that properly tested in large numbers.
That said, the barge is not going to be common. 10 at most are what I think will be on the server in the end. Them being able to jump to a different system every 24 hours or whatever would solve the issue of beaming.
