Just hiking to Everest Base Camp and nearby Kala Pattar (8.5 days, ~18,500 ft) was brutal for me -- and that was with porters carrying my heavier gear.
Hopefully this will save the lives of a few Sherpas (who, btw, are an ethnic group; it's not a job title). They're inevitably tasked with attempting to save rich Western idiots doing stupid stuff like climb Everest without support.
I'd just add my personal experience on the mountain: it's hard to describe how brutal Everest is. You're so cold and so tired and so out of it, 99% of us (those without natural-born mountaineering gifts) being up there unaided is just a recipe for disaster.
Next I'd like to see the Nepalese government double the Everest permit fee (currently $11,000) and pass $$ onto Sherpas.
Doubt it will happen, but this is at least a small victory.
