Now this is great Idea. But since am still learning the protocol I need
help to understand it better.
For the above case I will request property_get passing $criteria as
requested property and it should work
But what if the thing am watching is rather expression, something like
$x = $y+$z*$r where I want to watch expression
$y+$z*$r not $x. In such cases whats your advice?

Thanks a lot,
