Thanks all for the advice. As life would have it I got pulled in
another direction at the last minute. Andrew's description is probably
the one I was thinking the most about..using the uvtextureSOP and
working through the steps that way.

Lets assume the curve is linear, and along a cardinal axis like x. I'd push
the points into a semi-circle on the x/z plane and then resample along
polygon edge using even length segments. Finally scale by 0 in z to get the
new points back on x with that distribution.
The semi circular offset can be achieved using sin and cos of a normalized
UV attr scaled to pi. The uvtexture sop will give you that.
There might be more elegant ways...
