The people for whom a 16GB RE is genuinely useful right this second are 
few, they pretty much know who they are.

I will say  that having worked at a big security vendor even with 32 bit
userspace a 64 bit kernel buys you dramatically more headroom to
scale-userspace on the box, and the extra ram is basically the cheapest
part of the whole exercise.
