I've found a low cost NAS for my simple network but this SPECT-NAS is too good to be true. Take a good look at it http://www.leadingspect.com . How can a NAS be able to share application software?
(SPECT?-NAS can act as a Server that application software can be shared) .
While a NAS device does a lot of good things for storage, it is not designed to run with a great deal of processing power. That job is for the server. A NAS exists to serve up files, not to run programs.
