A good question. But market research of its potential usage is
also important, especially because of the 'divorce' between
Inmos transputers and occam.

I can't imagine any side effects *except* by the removal of features or the
alteration of semantics. So we should know what to expect from any
proposed changes. But Beta testing is clearly desirable, for a variety

That depends on whether OFA cultivates the Unix market sufficiently. I
think the possibilities are moderately good, especially if we can offer
novel approaches for (i) SMP programming (a credible alternative to Posix
lightweight threads), (ii) GUI programming, (iii) animation.

There is the distinct possibility that our own version of Java would have
even less impact than occam.

(1) I disagree with the understanding. (2) may be a flier, but my reservation
is that doing our own thing with Java is that of heading off in our own
direction again, rather than having a significant impact on the rest of the
world. Now if we could influence Sun to change the de facto Java standard,
that would be exciting!
