Right, that was my view exactly.
It means that, in the POWDER world, you could publish a description of "com" - i.e. everything on .com. It may be pretty meaningless, but, well, when did language stop people saying meaningless things? :-)
I don't think this is a problem for access-control, it just means that the author can target very wide audiences. But that's nothing new since he/she can already target <*>
It's tempting to try and add restrictions such as requiring at least a 2nd level domain. This might have the desired effect for .com, .org etc, but falls down in places where third level domains are the norm (.co.uk, .com.au, .com.cn etc.)
FWIW, i think UAs today keep lists of such two-level TLDs. I know mozilla does. It is useful in a number of circumstances.
