Dashboard vs konfabulator

You might remember when Apple released Sherlock, a blunt shameless rip off of Watson ? Well, as everyone knows, history repeats itself with the new Tiger feature called Dashboard, which seems to be the same animal as Konfabulator.
Same thing : making it possible to develop widgets in javascript and XML, with screen licking graphics.
One thing's for sure, Apple did not buy out the company behind Konfabulator nor did they hire the developers. Anyone else smelling some legal actions soon ?
Let us remind you that Konfabulator is developped by the same person that was behind kaleidoscope, Arlo Rose, who participated in parallel to the development of Apparence Manager of Mac OS 9.
And, while we are on the subject... Watson has just been sold by its author to a "large" company that still remains anonymous. This company should release a Watson based application by October 5th 2004. A few people are guessing that SUN is behind all this, rather than Apple. We'll see... but anyway : coincidence ?
