RB, thats a fantastic idea,
I had been thinking of doing something for myself along similar lines - with the thought process that if I did it, others might follow. The problem of multiple identities at a moot can be more than a little confusing so a name badge would ease the situation.
I've seen name tapes much that same as US forces are portrayed on TV, black embroidery on a green, edged badge/tape, surely they'd fit the bill.
I don't want to hurl this in Tony's face straight off, but perhaps it is something that could be offered as part of a membership deal, at extra cost of course. BCUK logo and a name, say a base cost for so many, with extras at a fixed price per unit over that.
Perhaps I've jumped the gun on this but in my mind, its a winner.
