I truly wish TiVo would offer that; I would buy such a product immediately, along with 2 Minis. I am on cable now but planning to go OTA-only in the near future, so I don't want to invest in a system (XL4) that prevents me from going that route. Buying 2 more Premiere's just for Mini-esq functionality means higher HW costs, higher TiVo service costs, higher Cable costs (2xCableCARDs), and higher power consumption costs. TiVo has not provided me any attractive roadmap. Thus the interest in this workaround solution, which I hope will get me by until TiVo releases such a DVR.
