We just released BlackBook - a server based contact management solution. You can take an export of your Now Contact data and import it right into BlackBook.
Just like Now Contact you can share contacts with those in your organization, but we also have some great features - such as a CardDAV server to get your contacts on your iOS device! We also have great relationship manager, allow you to easily get from one contact to another.
There is a 3-use trial available for download on our site www.autriv.com/products/blackbook
. The cost of the app is $99/user with the server being free.
Hope this helps everyone!
