Nope, sorry. There's no support for this, at least not in Carbon. (I don't know about Cocoa.)

It's a very "bad idea" in most instances, but sometimes it makes a lot of sense. To say it's wrong in all cases is closed-minded. For instance, an LSUIElement application can be firmly in control of the focused piece of UI without being the "frontmost application." It's stupid to prevent such an application from changing the cursor, yet Apple does.
I have worked around this limitation in FastScripts (although sometimes it doesn't seem to work and I haven't yet figured that out) by investigating and taking advantage of the "Apple Internal" hook that Apple exposes to let their own applications take advantage of this valid UI control. Below is an example of some code that you might benefit from. It goes without saying that this code is completely unsupported and might stop working at any time. Consider using it a form of civil disobedience:
long sysVers = GetSystemVersion();
// This trick doesn't work on 10.1
if (sysVers >= 0x1020)
void CGSSetConnectionProperty(int, int, int, int);
int CGSCreateCString(char *);
int propertyString, boolVal;
// Hack to make background cursor setting work
propertyString = CGSCreateCString("SetsCursorInBackground");
boolVal = CGSCreateBoolean(TRUE);
CGSSetConnectionProperty(_CGSDefaultConnection(), _CGSDefaultConnection(), propertyString, boolVal);
Is there a less tweaky way of doing this and I've simply fallen behind the times? Please let me (us, the developer community!) know...
