I don't really think the overall name should change, but just maybe the name of the 2 different units could be improved, so I voted no.  I like Shadow as the overall project name.  I also like "shade" as one possible alternative to "shadow tokens".  I like Shade without the "s" on the end, I think it sounds better.  I don't really like "lytes" or "lyte" that much for SDC, but its not bad.  But it may get confusing for people. Also it could be confused with litecoin and stuff.

One other suggestion I thought of would be "show".  Like send from "show" to "shadow", or send from "show" to "shade".  Or something like that.  The similarity between the letters in show and shadow would be an interesting play on words.  But I am not final on this either, just bouncing some suggestions around.  We could keep it as ShadowCoins, and use "shade" as substitue for "shadow tokens" and that might be good too.

Edit:  Or also from "shine" to "shadow" is another suggestion.
