I'm a little late to the party, but thought I would comment.

I will admit that at first I really disliked this idea. There is something distasteful about profiting from death. After giving it some thought, and looking over some of the memorials, I really think you have something. Of course the key will be to treat people fairly and with respect and kindness. I have seen the poor implementations currently used by funeral homes. Even those seem to be a true source of comfort for the family. Good luck, I hope you're successful.

It looks really nice. Small comment: On the main page for a memorial, when the box pops up asking if I know the person, it says "show your support". I found that phrasing a little odd, less heartfelt than I'd expect. I'd change it to 'show your love'.

"Love" might be a little too strong for people who were only marginally connected to the deceased.

Show your caring?

I don't like "caring" as a noun much. I think "support" is good -- it means "emotional support for the family", not "I support this dead dude, he was cool".
