"If poser didn't have animation but had better python scripting a good programmer could write a script in one day (I sound like a programmer now)to make it animate. (Yes it would be horrible to use but what would you expect for a days labor.)"

Well I wouldn't expect anything at all out of a days work on it - I also wouldn't actually USE it for anything. Grafting a multi-track keyframe, kinimatic aware, BVH compatible animation system on D|S with a Python script and have it be really usable and competitive?

Not in a day ... not in a lot of days.
