Please post a success or failure, if it looks like a strong candidate maybe tonymac or macman can look in to incorporating it in to multibeast, should be pretty straight forward to add 'FileNVRAM.dylib' to the modules folder.
From memory it was originally in MB but was removed to due to the filenvram authors request as he/she perceived MB to be a revenue raising program (through donations). Therefore, the author didnt like some other community making money off their work.
I could be wrong but thats what memory serves me anyway.
Regardless of any political play, I thank both this community and the author/s of FILENVRAM for allowing us to run our hackintoshes nearly perfect.
