If it's in Flash, you can make Aliased fonts with a Dynamic Text Box. Since everyone has Verdana, or Geneva(Mac), you can unselect any font-embedding. Then you'll have crisp 7Pt Verdana, in flash.
Else, in Photoshop for instance, in the type box there's a checkfield called 'Anti-Alias' or something. Unchekc it, and Verdana'll get crisp.
