Using the term PLL.

Slewing the clock is not a PLL.  PLL's need feedback.  There is no feedback 
involved in a simple slew.

What's the real problem with step rather than slew?

We should probably start a web page with a matrix of OS vs feature.  It would 
help to know what parts of a feature are important.

I didn't get the message from that blog that the problem was that making it 
work was going to involve too many complexities rather than a can't-fix road 
block.  But I probably wasn't looking for it.

How close did you get?

How much could we learn if we had something working to experiment with?
