Do you mean like Messiah's telescopic IK?

For only one bone, you could find the midpoint of each world coordinate [ (x1 + x2)/2 etc.]. You'd also need to use the target function to keep the bones in line. For more than one bone, a little more math would be required, but it would follow the same principle.

yth bone's X coord + ( y - 1 ) * (1st bone's X coord + nth bone's X coord) / ( n - 1 )

where n = number of total bones and y = the number of the bone that is > 1 and < n.

That's off the top of my head...
