Yes, it's a subscription, but I consider it a really cheap one: $10/ 3 months or $36/ year. I was already using it for boxing WoW, so it doesn't cost me any extra to use it with RoM also. But if your reason for playing RoM is that you are fundamentally opposed to paying subscriptions, then you may need to find a free software boxing alternative.

Zanthor has a good base tutorial for setting things up with IS and ISBoxer over here (plus his referer link to sign up with, and see if we can extend his account into the 22nd century): http://www.dual-boxing.com/forums/in...ht=#post197725

It's from his perspective as a wow player, but a whole lot of it translates for RoM, and if you just need a basic repeating profile for RoM with ISBoxer you can start from mine here and change the character names, and window swapping and reapeater on/off keys.
