I don't think any algorithm is ever going to solve that problem. It's not always possible for a human even to tell where to place beats, and sometimes there's multiple ways you could reasonably interpret the beats. And if you have an algorithm that works perfectly for gabber it probably won't work for folk, or ambient, or punk rock. And what if the time signature is not 4/4?. That's one of the reasons why you need a human to DJ well.
Traktor has beat grids for this purpose, perhaps we should think about doing those?
