I would like to implement a central configuration for use in a webfarm.

I could write my own code, but first I wanted to make sure there wasn't and code out there allready.

Instead of maybe there is something like SqlConfigurationManager.

I'm want use the existing configuration classes like configuration section.

Maybe I can store some xml in the table, and load the xml into a ConfigurationSection myself?

The simplest way would be to use the configSource attribute of the existing configuration elements:

<connectionStrings configSource="Config\connectionStrings.config" />

Then, just have the Config folder in each app be a virtual folder from a common location that your entire farm can see.

That would be a great idea, but there is one problem.

I have SectionGroups, and configSource is not supported in that case. I think it is a bug.
