Multple PC's and ISBoxer Licensing

I run one ISBoxer PC right now and plan to use it to 3-box a melee, healer and caster DPS.

But I have two side computers that run straight EQ. One is for a melee (that needs constant adjustment) and the other is an enchanter (which needs separate debuffs and mezzing). I really like the key mapping features in ISBoxer though -- they are impressive. Can I run ISBoxer on the other two PC's using my existing account/license, or do I need to purchase two more licenses?

Thanks in advance.

You can run Inner Space on up to 5 PCs. ISBoxer comes free with Inner Space. So, yes, your existing license covers what you want to do.
