Exporting Illustrator brushes

hey all,

is there a way to export an illustrator file (say as an eps or something) with brushes… basically i’ve used a brush on a stroke, and i’m worried that when someone else gets the file it won’t be there. I don’t seem to be able to “convert to outlines” because it’s already just a stroke really… is there a way to make the brush a vector object?

thanks
Stu
