I can imagine this to be a viable option for corona some time in the Future as a source of some additional income and/or clients... maybe...
But I would like to know for what reason would you want to have renderer in compositing software instead of your main 3Dapp. I would maybe like much more having a "Nuke" embed in a main package than having to load some enormous ammount of assets into Nuke and managing the whole scene there...
