Hey Ryan,
I've trained in Capoeira and DBMA. There are similarities between the footworks, but not as similar as you would think. The way I was trained in it, I actually had no pentrating steps, except on a teap like kick (I forgot what they called it because it's been a long time) See my post in the member section about this. I think that's why my Kali Tudo has entered into my footwork so easily. I'm similar to Guro Lonely in that I'm a footwork (counter fighter) based fighter. Interestingly enough, when I was using a Mark Hatmaker drill, I actually pulled off a Capoeira kick has a counter to a Teap which surprised everyone. I think Capoeira has application in certain areas such as a surprise attack, or angola Capoeira is another area I'd like to explore more (ground based attacks). Frank Shamrock has been known to use a variation of a Capoeira kick to defend from the ground with a standing opponent and Mark Hatmaker's material uses a similar kick and a defense from a Capoeira position. One kick I find highly useful is called S-batito. It's basically on all fours then transferring weight to one side of the body (hand and foot) and using a cartwheel like whip to kick across the body which ends you up at standing. E-mail me sometime. Maybe, I'll make a video of the similarities.
