I wonder, what if someone RP's a Battlegroup and uses the PoB as some kind of Battleship placement and then asks it to be moved as some sort of inRP placement of their "fleet" which would also act as a Mobile Base.
Guess if they could RP justify their moves like that plus what Snakfree said about 500M, it could be done. However about regular RPed Bases/Stations it's a tricky question.
