If the code is something that is useful across scientific fields, then IMO
it can be bundled with Scipy.

In this case, we have the misfortune of knowing beforehand
that the algorithm is patented in US, and although as ridiculous
it is, this makes the code poisonous for many US-based users.
So, I'd say that this cannot be included in Scipy which does
have US-based users and redistributors...

The information on that page is a bit outdated. This one is more up to date:


Note that being a "SciKit" is mostly just a matter of branding --- you make a  
separate Python package from your code as usual (which you seem to be working 
towards), call it "PyHHT Scikit", and add it to the "Topical software" list at 

We earlier recommended naming the package as "scikits.XXX" but this
turned out to bring in some technical problems in the long run, so
that part is optional.

Without the patent issues, scipy.signal would be the correct location.
I'm not sure if scikit.signal is dead or just sleeping.
