Archetypes tubeless?

By going tubeless you'll be limiting your tyre options as road tubeless tyres aren't common yet .. and I'm sure I read somewhere you can't just 'ghetto' clincher road tyres like you can MTB tyres because of the extra air pressure needed lifting the bead.

I don't see how I'm limiting myself, really. Until there are more tubeless tyres on the market, I can run standard tyre/tube. When tubeless tyres are more prevalent, I can put them on. I was just wondering if anyone had had any success doing it yet.
