Okay - got it, you don't like laminate.
I googled 'prefinished floating bamboo floor" and came up with some hits. One link is below - Premium Green, glueless click lock installation, can be floated, glued or nailed down. So yes, you can do a floating bamboo floor that is a press fit joint with no glue required.
The first few on the page are glue or nail down, the floatng options are further down the page.
