One small business for two very different methods of income?

Is there any sort of disadvantage or legal ramifications to selling two very unrelated products and dealing with the income through a single sole-proprietorship?



A couple hobbies are about to make some money soon and I just want to simplify things and apply for a small business to deal with taxes, licenses and such.



Would selling smart phone app's/videogames/software and live earthworms under the same company be wise?
