We didn't contact them. We thought about possible problems of the name,
but decided we shouldn't worry.
The Apache server is free, nobody's exploiting the name for profit, at
the expense of the Apache people.
I'm sure if we called it the "English", "Welsh", "French"... server,
none of those nations would feel hurt in any way. Why should the
Apache feel any different ?. Suggesting they might feel differently
is probably a bigger insult to them than using the name.
