Indeed, first mooted about 20yrs ago.
MUAC is the subject of institutional change at the moment, with the possibility of a split from Eurocontrol in Brussels to continue on as a separate international organisation as well as a few other options - simply being 'taken over' by DFS is not one of the options and quite frankly never will be, as:
1. It is not a private organisation for sale
2. The Dutch government have already stated they will not relinquish their stake/control
3. In a FABEC context the French have already VETOd any private ownership option.
Im pretty certain MUAC will get a name change in the next 5-10yrs and probably fall outside the Eurocontrol umbrella - but not under ownership of the DFS!
