Does anyone know if GMS can install a client onto a blackberry?

I'm using GMS 2.0.2 I've been searching for info on this and everything
points to using BES even though there are vague hints at GMS supporting

I would much rather use GMS as it is installed and configured plus I don't
have another box to install another API for 1 user.

Which would lead to a second question can GMS and BES exist on the same
box if needed ?
