I doubt if this wish would prove economical for Graphisoft, as lack of network rendering is probably not anything that is either limiting sales, or limiting upgrades... and the development cost for your wish could be substantial.
Graphisoft's answer for network rendering (at an additional cost to the user of course) is to use Cinema 4D, which is what Cinerender is based on, and perform network rendering there:
Of course, there are other products such as Artlantis, Twin Motion, etc for external rendering as well.
For most users, the built-in Cinerender is adequate, and you can set up your renders in publisher sets to batch render overnight so that you don't need to be concerned about your computer slowing down while you are in front of it.
