Having it in the system will help other applications to do DNS queries faster (e.g., asterisk, mail servers ...). It looks to be really powerful being able to cache many services, not only DNS. It comes packaged with most of common distributions.

nscd is part of GNU C Library, I am sure a lot of people will be happy 
to learn about and many will strive to fix as soon as possible, if you 
can describe the issues you had with it -- it is part of a core 
component in all Unixes.

Also, the name of the other one and the issues will help the developers 
to make it better -- testing and feedback is the most appreciated.

Cheers,
Daniel
