locally run app

locally run app

It would nice to be able to install something like this on a central shared computer (server), without starting a daemon, that would be a simple install. (and a simple database!) ie just click 5 times and installed!
or
is there something already out there?

this would more easily address issue of : local ie faster, not relying on the internet, security, maybe do own customization.

just ideas. any thoughts?
