Nope, no fake moss. And haven't had any brown moss :P Course, again, our setup is different. We have a water side, so the glass insert might be catching a lot of the splashes since the water level is about an inch lower. Whatever the case though, we've definitely had a water side without drenched soil.

Actually, come to think of it, one good idea that you could use for one of those self-contained fountains is to buy one of the larger sitting ponds (you know, the ones that are about an inch in height), and put that underneath. That might catch a lot of the splashes, and give the frogs just another place to lounge.
