Disabling vassal states after x-time?

[Thrax]

I am looking into a possibility of removing vassal-treaty's from the game after a certain technological discovery. Much like the manhatten project enables nukes for all.

Example: United Nations gets build, vassal treaties are void. All countries are free.

Example2: Nationalism is discovered, nations revolt, declare independance and even war upon their oppressors.

this large part was done in rhye's and falls mod. Just i cannot figure out if how he done it

Tech_Feudalism grants vassaltrading 1..now to remove that.

Any lead on where i should look?

I suspect you'd have to modify the [C++] source to enable such a feature.
