Forum OpenACS Q&A: Re: Setting server configuration parameters during runtime to avoid reboot
The module has a Tcl and a C-level interface. So if all you want is the Tcl-level access, it does pretty much what you want. The C-level code of the main NaviServer modules does not use this for obvious reasons, and as mentioned before, changing the configuration value is simple compared to handling the consequences of configuration changes (implementing the e.g. life migration semantics of a change of a driver/db-port, of an ip-address, change of modules, ...). So in order to make this really useful, one would have to add as well callbacks for value-changes that address such issues on a per-parameter basis.
