Not that I am a strong fan of the ethnicity results page that Ancestry does, but I believe there is an option for that to be shared out to anyone. I haven't done it, but I remember reading a blog post very recently about this. Somehow there is a tool button on the ethnicity results page and you have the option to share it out, similar to how you can share out your posted tree to a guest.
(I tend to order and do my tests at Ancestry, and then upload them to both FTDNA and GedMatch for the maximum benefit from one test. Yes I am missing out on the 23&Me crowd, but the serious ones will have loaded to GedMatch anyway. Currently it is 4 tests, but the 5th is waiting on my table for it to be done by the next person on my list.)
