Isn't it something Red Hat did a long time ago that was widely regarded as a Very Bad Idea?

And why would you use HTTP in this scenario anyway?

I don't know why it didn't work out for Red Hat but it works quite well on Windows. And honestly I don't know whether they use(d) HTTP or not, but given that HTTP is dead simple and as lightweight as a protocol could get, maybe it wouldn't be such a bad idea to use it for exchanging messages in this scenario.
