LOCAL or RLM?

Sales told me to post this question here as they couldn’t answer it so hopefully someone will help me with this as I’m an lowly animator and not a tech at all (www.screamingpixels.com). I just bought the local version of MR and am wondering whether I purchased the correct version of MR for my needs. I also just bought Shave from Joe alter and want to render that in the normal Maya command prompt using MR. Sounds like with the version i purchased I have to use the standalone MR and really don’t want to have to learn something new as I’m on a deadline here. So the question is, can I render Shave in a Maya scene with MR from the normal command prompt with the version i purchased? Or should I have purchased the RLM version with a floating license? Thanks for helping keep me straight on this.
