Is there a "universal speed limit" lower than the speed of light for an object of a given mass?

Let's say there's a 100kg object traveling through space. Obviously it can't reach the speed of light because it has mass. But since we know its mass, do we know how fast it *can* go according to the laws of physics? Or could it theoretically reach 99.9999999% of *c* but just never quite reach *c*?

An object of non-zero mass can in principle attain any speed less than the speed of light.  

In fact, since velocity has only a relative meaning, there are frames of reference in which an object of non-zero mass has whatever speed less than *c* you wish.
