Very limited. Not much on the wide side. I think he means something like an HTS for Phase bodies.
Note that the HTS imposes a 1.5X magnification on the lens, so the widest it will go is 42mm [HCD28mm x 1.5].
In addition to Schneider/Rodenstock/etc lenses listed above the X-2 can accept all RZ lenses including the 50mm with focus to infinity. The X-2 retails for around $2500 depending on which lens boards and camera mounts you need.
That said - you're absolutely right - it is a limited solution on the wide end and not our recommendation for most interior/architecture/wide-angle-landscape work. For such wide angle work the best technical solution will always be a mirror-less solution such as a Cambo Wide RS (i.e. not an SLR) as the best wide-angle glass (as Dick points out) is either non retro focus or very lightly retro focus and requires a small distance to the sensor which precludes an SLR design.
Also note that you can slap just about any lens from any manufacturer of any length on an X-2 (with appropriate adapter and/or gaffe tape), but only the "compatible" lenses will focus at infinity. It is excellent therefore for table-top, product, special effects, specialized portrait etc.
