I suppose that a market for the thing exists but at 65USD i'd bet it is pretty small. Even if I liked the idea of what he is trying to do the lack of not just an ashtray but means to mount one and the coal/head issue I mentioned before would make not buy it even if I felt the price was sensible.
If I plan on smoking at a party I either bring one of my own rigs or cigar. A friend of mine has one of those Syrian narghile tables I talked about a while and I often use that when I visit. Some things are just not meant to to be done on the go and mu'essel smoking is one of them.
