Grant per node access for anonymous

Hey,

first at all, after great issues with the Tac- and other Access-Modules Content Access is very simple an powerful, nice work!

I already searched the other issues, but don't find a possibility to grant node access for anonymous per node. I need it for a File-Type with Bitstream, that's the reason why I can't create a new content type. Further more, other issues tell, that you ban anonymous per node an give him overall access, but I think my users won't "check" that ;) Maybe it's possible to add this feature, that would be very nice,

thank in advance,
