In a distributed and/or decentralized system 100, a central entity, such as a remote and/or control feature adjustment module 104 and/or a hardware testing server device 102, 108, in certain embodiments, may still provide, to one or more feature adjustment modules 104, one or more messages comprising instructions for automated testing, remote user input for testing, adjusted and/or updated parameters of a scene tree, or the like. In a further embodiment, one or more feature adjustment modules 104 may pass messages to each other, such as instructions for automated testing, remote user input for automated testing, adjusted and/or updated parameters of a scene tree, or the like, in a peer-to-peer manner. In another embodiment, a central entity, such as a feature adjustment module 104, may initially seed one or more sets of instructions and/or other data for automated testing, and the one or more feature adjustment modules 104 may send it to other feature adjustment modules 104.
