Joe -

I surely might be missing something, but this problem looks like
it could be solved very effectively by using a linked list of
structures. This would make it very easy to insert or append
nodes, and you could "sort" your nodes by keeping an array of
pointers to the nodes, and just sort the pointers (instead of
the structures, which is inefficient).
