This, in my opinion has been well thought out. Very easy to use and absolutely nothing to install. Just run the binary. I have been using Minefield since pre-alpha on my BAMT rigs. It has come a long way in a very short time (matter of weeks). This program has saved me a lot of time being able to enter my pools at a central location and be able to accurately re-direct my farm to a pool with 4 mouse clicks.
If you have multiple linux rigs and hate having to login to each of them to switch pools, etc give MineField a try. If you like it, donate like I did to further development
