Is Wasco Sans font by Jim Wasco available as a web font?
Wasco Sans is a custom font that was designed for Microsoft. While it seems to be freely available for use for games developed in XNA Game Studio, I can't seem to find it anywhere else on Ascender's site. Since they made the font and sell web fonts on their site, I'd say it's safe to assume that Wasco Sans is not available for web font usage.
