I'd think that despite variations in environments in a home, there are either 1) enough accommodating tools to normalize (e.g., lights that have a variety of settings) or 2) the majority of the processes required to handle the variations are figured out (e.g., in consistently poor lighting, you need package B instead of package A).
I see some hardware packages for home studios going on sale, but nothing to the level of hardware/software integration necessary for the most effective online instruction/discussion.
