Though I don't sell it, Colorburst Overdrive makes exclusive use of printer mfr RGB media sets, no CMYK or CMYKn. EFI eXpress or Fiery XF (which I do sell) have embedded RGB drivers for a number of models. I have not made a survey of all the RIPs that have RGB drivers. One requirement is that the printer model actually has RGB input. This is the case for all the "photo" printers from Epson, Canon, HP. Production printers (Mutoh, Mimaki, Roland, HP Scitex, VUTEk, Durst, et al) typically have no RGB input .and one must drive them with a RIP in CMYK or CMYKn. My shopping advice: All RIPs that use RGB output are using the same maufacturer-written drivers, so base your decision on other features and price. RIPS, especially for fine-art and signage applications, are mainly about productivity and not color, and this extends to RGB printing as well. (Please no deluge of claims from RIP mfrs on superior color from their CM engines, or about proofing--or begin a new thread for it!)

HP's black and gray inks are, unlike Epsons, quite neutral, and this lends itself to extremely aggressive GCR, which is applied behind the scenes. With Grayscale images or even RGB grays the GCR is 100% and they are processed with black and gray inks only. When matte media are selected the matte black and 2 grays are used but also the photo black ink, which being slightly less dense on matter media serves as a dark gray, so it's a quad-tone. Pretty elegant. On the other hand the Z31/3200 are not driven so nicely by some third-party RIPs: gamut is smaller, with less smooth boundaries. The best solution, I've found, is to use a RIP that has incorporated the HP RGB driver; then one has all the productivity of a RIP (nesting, tiling, hotfolders and multiple print queues, foolproof color presets, etc.) plus the superior screening and color output of the RGB driver. Inside the RIP one still must select the media type as in HP's driver. The same approach can be used with some Epson and Canon models--many RIPs now are including RGB drivers.
