[SLUG] DNS Appliances/Web Frontends

[UnspecifiedId <unspecifiedid@xxxxxxxxxx>]

Greetings,

a) can anyone recommend a good virtual DNS appliance with a decent Web  
GUI frontend or
b) good Web Front ends for DNS. I was thinking of looking at MyDNS,  
MyDNSConfig

either needs to have the ability to do zone transfers. Any  
recommendations or thoughts would be greatly appreciated.

Regards
