All of NVDA's in-process code should be unified into NVDAHelper. This will reduce duplicated code and greatly ease the process of adding new in-process code. NVDAHelper will handle the setting of system hooks and components will then register hook callbacks with NVDAHelper to be executed when the hook is fired. nvVBufLib will be merged into NVDAHelper, which means it will no longer be a separate library. This is becoming far too difficult to maintain and the advantages greatly outweigh the disadvantages.
Most of this work is already complete. However, we should be tracking these issues properly. :)
