Pauli,
It's easy to uniformize non-uniform grids, see
[Intergrid](http://denis-bz.github.com/docs/intergrid.html)
(comments welcome).
Sure, for order > 1 this is not as smooth as real non-uniform splines
but very simple, low-memory too, fast:
in 4d, 5d, 6d, Intergrid does around 3M, 2M, .8M interpolations / second.
a bird in the hand.
cheers
