FOR NOW the FTC is only demanding "one page" and a few things. That's typically how big government starts, sounding reasonable, requiring little. The principle they are laying down, however, is that they have jurisdiction over all internet commerce, and get to unilaterally rule as to what their rules mean, is absolute. Today a guppy, tomorrow, they'll be back the size of Godzilla, demanding to know everywhere the site keeps money, tax forms, id cards and documentation, compliance with 6-7 other agency regs, etc. Will you have to be a "licensed work-at-home" provider some day to offer a course? Could be, who knows.
I'd set up some offshore domains/subdomains, hosting and payment processor funnels, just in case.
