I dunno. Now that I think about it a bit more, compressing all of your possessions into a singularity might not be the way to go. I mean, it's a space-saver and all that (not having to bend over and take it from U-Haul: priceless), but how do you get it all back?

I bet the math is complicated. It might be easier to just pack.

With that said, The Postal Singularity is a concept that needs a story attached to it, unlike this revolting dreck of BabyLaurell's. Or maybe it's been done. (http://www.amazon.com/Going-Postal-Terry-Pratchett/dp/0060502932/ref=pd_bbs_sr_1?ie=UTF8&s=books&qid=1221177449&sr=8-1)
