come on, as someone stated in other thread the licence doesn't even
appear legal in europe, so what do you expect?

Note that if I would be buying a BK non-free licence the "restrictions"
would go away AFIK. However Miles (on the arch list) tries to buy one
(exactly so he could test BK) and he failed to get one.

"no free use" may be less restrictive than the "free licence". You pay
to get more freedom, which sounds fair.

either you're completely wrong or Larry did not protect any IP.

Larry said in an earlier email today: "we have to protect our IP.
Rightly or wrongly, we feel we did some new work that is worth
protecting.".

don't get me wrong, I've nothing against protecting IP, but my point is
how can he protect IP if I can use BK, learn all the features, then the
next day I stop using them and contribute to another SCM after the
knowledge learned? I mean, there must be a delay between the two events
otherwise what a protection is that. I can use BK the next second I stop
using BK and I make a patch to arch, the next second I use BK again.

I would be *very* happy if you were right in the way you interpret the
licence, if Larry could confirm you didn't misread the licence, I could
sure use bitkeeper too (at least to try it once, you know I may be
curious about testing bk speed after all these talks).

But I'm not attempting that unless Larry confirms I can learn using bk
and immediatly after I can contribute to arch or some other SCM to
possibly implement overlapping features (and so far I clearly understood
this was not possible, and this is also why it didn't look legal in
europe but IANAL).
