Does anybody know if one butter bot license allows it to run simultaneously on multiple machines?
I'd like to have it running 24/7 on my desktop at home, while being able to check test change settings while traveling.
This isn't really a good idea. Multiple instances of the bot will trample on each other, as they all try do act on the information they have (the bot won't know that other instances exist, so it will try to make duplicate trades, etc., and create a big mess)
I'd suggest setting the bot up on a machine at home, and then configuring yourself with a remote login system such as LogMeIn so that you can connect to that machine and monitor the bot.
I leave my bot running on a home PC, and use a VNC server to connect to it when I'm on the road.
