Suggest you look at BAe Systems past history on 'kick backs' etc. - in fact this whole Tanzania issue appears to revolve around such inferences...that is why operators will never pay nav charges direct to them or people like them!
I would suggest an ICAO sponsored collection system which could/would then pay to local nav service agencies and/or sub contract to specialist ATC providers where the local provision is inadequate or infrastructure is incomplete...supplying a full turnkey personnel/equipment package or augmenting local capabilities as required such as SERCO, Johnson Control (if they still exist?), UK NATS et al for example...
