Talked this over on IRC, but the bottom like is Key IPOs don't behave 
like other IPOs.  They currently all return "Key" as their name, so you 
can't use getCurve() or delCurve() and have it do what you expect.

Seems like the only way to handle is to pass an integer adrcode to it, 
since that's maybe the only way to uniquely identify the curve (BTW, 
Shape Keys can be named anything, so you *could* name them all "Key" or 
"Bruce" if you wanted to).
