Fluidtime - make a date with a washing machine via SMS

Thankfully our days of sharing a washing machine with fifty other people in the dorms are long, long behind us, but for those of you still negotiating wash-time with fellow students or apartment-dwellers, here's a new way to do it: Fluidtime, a social app that lets you reserve a time slot for the machine via SMS, and even negotiate with others to get your reservation bumped up if you need the machine in a hurry
(like if you've, oh nevermind). The developers envision Fluidtime as a full-fledged scheduling tool for shared resources; other applications include booking bus tickets and making doctor's appointments.
