I'm curious to hear other's thoughts on they think would be useful.
Please don't hold back ideas! There's very little harm positing silly or unlikely ideas, but there is some potential value (perhaps more than you realize).
Inspired in part by calebo's comment here
While I like this idea, I'm kind of surprised it reached the top here. I'm curious; do other commenters have come across many people who this would have been helpful for? Can people describe these cases a bit, along with what kind of loan setup would have been most useful?
