Sniper dolls -- not unique to Sniper, obviously...?

[frobisherw]

So I just had the thought: the technology/industry for creating Sniper's dolls (i.e. synthetic duplicates) has got to be much more widely available than is explicitly mentioned in the books. Even if Sniper, Inc. (or whatever organization it uses to manufacture the dolls) has some unique tricks and advances, the basic technology certainly isn't limited to copying that one individual. But if it isn't ... who else might be (or be using) copies?

The most obvious candidate, of course, is Kraye.
