That is fantastic news. :-)

And about it being boring, well, having been a researcher I have a true
passion for super-fancy and super-complicated schedulers, with
astonishing theoretical foundations... Despite the fact that they tend
not to work in practice! :-D

That is why, especially after having left academia, I developed a true
passion for small and simple schedulers that work too! :-P

Anyway, that thing about determinism (i.e., what are those properties,
why and where they are useful, etc), is definitely something worth
talking about in the blog post.

Well, that would be great, yes.

Ok, so why don't we get started and, when you'll be done, we will see
when exactly to publish it.

For being able to write a post you should go to our blog Website and
create an account. It's a Wordpress instance and it's here
(http://blog.xen.org/)... It should be pretty straightforward.

Once you have a userid, send it to me in an e-mail, and I can give you
the required permissions to start writing an article. While writing, and
also when finished, save it as a draft and send a link to the draft
itself either to me or (even better!) to this list, for letting people
review it (just like with code).

If you encounter any issue, do not hesitate to ask.
