Using Genesis theme demos on our site

[Alchemy]

We are going to focus in Genesis themes and would like to be able to show our clients the choice of "out of the box" themes.
Can we display the genesis themes via iframe so it comes up with our branding vs studiopress. We'll be clearly stating and linking to the studiopress site, but we don't want to confuse our clients too much with branding etc. As it is most of them have never heard of wordpress, thems, plugins etc so its a lot to explain.

We'd be happy to only do this in a sign-in members area but wanted to check with you guys if this was OK and your preferred way for us to do this
Thanks
