Digital BW, The Print

For BO printing why not simply make RGB profiles? I realize it's not
as whiz bang but it will have all the tags you are after, preview very
nicely, etc..
You'd probably be limited to printing out of adobe or other apps that
allow conversion before handing off but I'll bet that's most people
here anyway.
You'll have an on-the-fly conversion from grayscale to the RGB
profile, that then printed with BO, but so what?
