This was being discussed in a topic before with myself, EdB, and blueyed, but i can't seem to find the topic again.

Anyway, say I have a plugin, it allows multiple installs, with each install representing a install for a blog.

So we have the blog id setting in the plugin, and then the additional settings for whatever the purpose of the plugin is.

Now how do we stop the plugin from using conflicting blog ids?

As I would like to get into this, and I would be using a range for the blog ids, eg. from blog 1 to blog 5 (inclusive or exclusive) this plugin applies.

So how do I stop plugins later on from being applied to a blog that has the plugin already applied to it?
