Wildcard DNS (pros and cons)

[JimH@Nucleus.com]

What is the purpoase of allowing *.example.com within a DNS Zone?  Is there 
any pros or cons in allowing this sort of thing?

I have never been a fan of wildcarding, and now people are asking for this, 
and before getting in out my head I want to investigate this "feature"


I can think of one con.. if your charging for DNS changes then they would 
never have to contact you, but they could also just run there own DNS and 
manage themselves.
