This one guy I met did birder gaurd duty in Berlin during the cold war. They'd swap whiskey for vodka with their East Geman counterparts. And they'd drink with each other and talk from time to time. That's when he first heard of systema, although he said that the regular grunt stuff wasn't for skilled fighters, although the version the spetsnaz got was a other matter entirely.
This was at a Radio Shack a couple years ago, when I was picking up supplies for the trip to russia. He was the owner of the store, and the guy behind the counter was into eagle claw - although he claimed it was too deadly to spar with, what with using joint locks and all... I just smiled politely.
One of the guys at my club is born of Serbian parents. When he came back from his first class, he mentioned to his dad what he did, and his dad goes (paraphrase of a translation) "But this is hill fighting! We used to do this when we looked after sheep in the mountains. You are a city boy, why are you fighting like a farmer?"
Apparently there's some kind of poofy pants involved, and they'd hit each other with sticks too.
Of course, this is all hearsay, but fwiw...
Also, I have heard of BelloRussian styles, Ukrainian, Armenian, etc.
If you go to the ROSS site, you'll find a massive amount of links, which hook into the Russian part of the net. I use Systran to translate the pages, although you can also use Alta Vista. From there you will find mention of many various schools, and a lot of expired links. There's manuals on baton use, tons and tons of stuff.
