Not really.  It's the same basic thing -- as long as we're talking grayscale
input and RGB output workflow that you've used for a long time.  An RGB to
RGB transformation can be 3 dimensional i.e. the R output can depend on all
3 input RGB channels.

Some details are a little different:
In PS you are limited to number of points (14 isn't it?).
The point values are just 8 bit (0 to 255), but the interpolation is 16-bit
as long as your data is 16 bit.
CMM can have more points and they are 16bit, but the points have to be
evenly spaced.
PS uses nice smooth cubic splines to connect points, CMM uses just simple 
linear interpolation.
