BeOS Revival ?

A company named yellowTAB has just released version 1.0 of their OS named Zeta. Zeta is based on the original source code by Be, Inc. OSNews has posted a review of Zeta 1.0 and it looks like it totally rocks ? If you're, like me, a BeOS fan, you should look at haiku-os.org. These guys are developing an open source BeOS lookalike which is binary and source compatible with BeOS r5. Seems like BeOS is indeed heading for a revival of sorts. I, for one, would love to atleast see the live queries functionality of BFS (BeOS file system) being incorporated in the current OSs. Apple has made progress on that front with spotlight and beagle on linux also looks headed on the same path.
