Do let us know if you do :)
However, I'd also point out that when running CAKE a lot of these kinds
of setups become simply redundant. For home networks most of the setups
I have seen with such rule-based shaping is simply there to paper over
the underlying bufferbloat issue. Once you solve that you don't really
need all the policy-based stuff.
Now, there are of course exceptions to this where a strict rule-based
shaping *is* really needed; but HTB already provides this in the kernel,
and we don't want to re-invent that, so I'm not sure we'll ever support
this properly in CAKE, sadly...
