Questions about Apache License (fwd)

[Rob Hartill <ha...@ooo.lanl.gov>]

If he doesn't hear from us within a week, I've told him to assume he
can go ahead.

I can't work out if this acceptable or not.

Keeping the modifications and original Apache separate *seems* acceptable
to me, it at least ensures that if others do similar things, the customer
sees they are getting "Free Apache" + paid for work. For this to work, we
also need to stop the customer selling the combined product to others.
