Yeah, Hyperion gave us this speech that OS4 is a single-user system and doesn't need all that multi-user stuff. That stuff isn't just intended to let more than one person use a computer. It's a complete framework for secure networking. Not giving OS4 any muti-user capabilies is a big, big mistake, in the same way that Windows and Mac were very slow to realize the importance of networking and the Internet.
Question...is it that Hyperion has no intention of ever adding these features, or is it that that much of an OS overhaul is simply too much work for getting into the OS4.0 release? Your message makes it sound like the former.
