I'm afraid I still don't see why this would stop people from upgrading to
PHP4.  From an end-users point of view, there is no difference - it is still
free for both commercial and non-commercial use.  The only restriction is
that they can't modify the Zend portion, which I'm sure 99.9999% of users will
never need to do.

I certainly don't begrudge the PHP/Zend team the attempt to get paid for
their development time.

Heh; and here's me trying to help get RID of GPL stuff like readline, with BSD
replacements like libedit so that we can escape the GPL ;-)

I'd be amazed if any team could pick up PHP3 and implement PHP4 features;]
it's a complete rewrite.
