Has anyone used the new Lithium Polymer batteries yet? They seem to be
    the only thing out there that can compete with NiMH for capacity per
    mass at high current drains (>1C).

Surely the "regular" Li-ion cells have similar capacity?  I guess they're a
bit scarier to actually use, whereas the li-poly holds the potential for
being available to ordinary consumers.


    I found one company that claims to make them (Ultralife) but when I
    called one of their distributors, they said they would have to get
    back to me and have not done so yet.

There was some discussion here back in february; bare-ish li-poly batteries
are already being sold in the (ultralight) model airplane community:
