It does allow some very interesting abilities too. I used it for a
line-follower, where three tasks could dynamicly alter their priority depending
on what was going on. Another use would be a multi-goal system. For instance,
one task could be trying to follow a lightsource, while another is responsible
for getting the robot ("animal") to rest. When it has been too long without
"sleep", the task raises its own priority and tries to acquire control of the
entire system. A lot of fun "behavioral" possibilities.
