Yes I agree, and I've been bending my mind to try
to come up with something that will enable me to
do something like a sphere sweep in there.

The problem is that the center of the "hose" does not
lie on a straight line anymore when it is being pushed.

I think that maybe one could try to find the slope and 
direction of the line in the region where the current 
point is and then try to find the point on that line
that is closest to the current point.

And then (I think) one could sample the "pushing" 
pattern in front and behind the point that are used to 
decide the "pushing" amount, in order to estimate the 
slope.

But again:
My PC is to slow to let me explore this :(

(And I don't feel for doing this right now either :)
