Ok, how about using google's grab cursor? using something like:

```cursor: url(https://mail.google.com/mail/images/2/openhand.cur)```
and
```cursor: url(https://mail.google.com/mail/images/2/closedhand.cur)```

I don't know about the licensing and if you can use those icons, so I'm not sure. 

Maybe IE can just have a ```cursor: pointer``` and a ```cursor: move``` instead?
