I'm sold.

Lower power is a decent counterrequirement to promiscuity and injection. OTOH, we've got a bit of a hacker bias on this group of developers. If OM later sees a comparable or nearly comparable device that has those features, perhaps a poll could be run to get an idea of what people would want? > You know there has been a run of mails I am writing lately and the > thread is the same all over, closed stuff is making the trouble.

It's too bad we can't get the openness we're seeing out of Sun for their opensparc project :-) ... unless OM wants to go sparc anytime soon :-P -- H.
