Doh. I never found those posts when I was checking if anyone had done this - I guess I did it the hard way... didn't use LSTools at all. But just maybe my efforts can help us get animations.
I used Deliverator's scripts (

Then I used NexusBuddy (

Here's the intriguing bit with this approach - the NB2 format *does* contain animation and the NexusBuddy does have a "save anim" to GR2 option. So if that works we may have a way to get animations (until Norbyte cooks up something even better).
I'll see if I can successfully get an anim saved now...
PS
I exported my .bullet directly from Blender using the custom python script method shown in this video (https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=5&cad=rja&uact=8&ved=0CFIQtwIwBA&url=http%3A%2F%2Fwww.youtube.com%2Fwatch%3Fv%3Dfv-Oq5oe8Nw&ei=aqY0VMyjMsSlyATGzoCQDA&usg=AFQjCNGCdpKzC0cJmv0dEDZRxZLKhRFw7w). I'd give some explanation of what he's doing in the video since there's no sound, but I bet LSTools is *way* easier than this method anyway.
