Suppose you install it in a shared hosting environment. There will still 
only be one machine, but with multiple ip addresses (and hostnames).

www.customer1.com and www.customer2.com point to the same (physical) 
machine, but use different IP addresses.
for this reason a default like you point it out cannot work (or rather, 
will fail in such circumstances). It is imaginable that in such 
circumstances, we would have one ht://Dig installation with different 
config files for every customer.

We therefore need to ask for the hostname to use, bearing in mind there 
may be multriple.

What you point out (tower resolving to 192.168.0.29) is a feature of  
your local dns config (you might have bind configured that way, or have 
it in /etc/hosts) is a behaviour we cannot rely on. I don't know how it 
would work in a BSD-like envirnoment, or with MacOS..

What I therefore propose to do (for debian at least) is to use debconf 
to handle this, and to ask the user what they want. Whether the same 
mechanism can be used outside debian I am usure, since I don't know how 
portable debconf is.
