Neat concept but I can't help but wonder whether selling the domain and donating the profits to an actual charity wouldn't be a better use of the "funds". Or just not renewing the domain and donating that $10 to the charity of your choice in perpetuity...
This could happen here also. Creating a familiarity. So even if a person is initially irritated, after a month when he / she goes to make a donation, it would be to a charity that is familiar than a completely unknown one.
But buying SEO juice with unused domains the same way spammers do is probably a better idea - then a google search is going to turn up the correct sites.
Is there research to confirm this?
It could be that people's willingness to respond to "internet begging" doesn't tend to zero but rather a nonzero constant as they encounter more of it. In that case you'd be better off with more websites that do it.

Theoretically it absolutely could, in reality, it's hard to say but I wouldn't be overly enthused about people pointing random domains at any site I owned.
In short, Not to trash the people behind it, it is really well intentioned and I love the concept but reality may pose problems that end up doing more harm than good.
A cause would only seeing referring traffic when it's promoted as the top cause of the day. Links onsite at Domains4Good from cause submissions would also ultimately add to SEO value. Social referring traffic through Domains4Good promotions across all channels, not just redirect, will add value as well.
Not that I tested it or anything.
