Background, this is for a Mac and eventually Linux and Windows project. I have QT 4.6 and can control the version of QT used on the endpoints.
Working on a design where I will have some data that will be managed by a program running with elevated privileges, potentially root (or its equivalent, sorry coming from a Unix background). I would like to have some processes talk to this data manager, things like a UI to update data. Ideally these run with no real privileges, so anyone on the box can use them. My first thought was to use QLocalServer but this does not seem to work due to permission issues.
So imagine something my my_manager running as root (or a user account generated for this purpose like httpd for Apache) along with a UI program run by some user account and potentially a little binary or two kicked off by cron or its equivalent.
Do I need to switch to a TCP (or UDP) solution even though all of the components will only ever run on the same machine?
It looks like Trolltech (Nokia, whichever) is working on improving the IPC support in the framework, but it is not ready for real use. Is there something I have missed?
