We do it all the time in both directions. Since we are always showing home theater products TV makers often ask us to use their TVs in our demo rooms. Vice versa we often place our product in our partners booth. At a recent trade show we had a product in a Google booth, another product in a Dolby booth, speakers in multiple receiver maker booths, and in a few distributors. I recommend finding someone in event marketing or sales at the company you want to partner with.
