One additional point that I don't think was made yet is that you're starting a new shard. I think it's common to spend a while getting everything set up or tweaked the way you think it should be. In addition, it'll take a bit to get your player base up. So with only a few players, you can bank that they won't be too upset if it crashes every so often (which shouldn't happen even with the RunUO 2.0 RC1 or most of the svn updates).
Perhaps by the time, everything is "done" and players are trickling into your shard, a new RunUO release will happen.
