I have a new website and I was wondering about the license specifics regarding Segoe UI, a font Microsoft uses on lots of stuff. Do I need a license if I use the font in any way on a website, or do I only need a license if I use in in a @font-face manner? If so, what is a cheap way to get a license/how can I get one?
The official answer is,
Please fill out the form below to contact Monotype Imaging regarding our various font license extensions for multiple workstations, servers or enterprise-wide applications. We will respond promptly to all inquiries. Thank you.
They do mention the usage on web server explicitly, so I'd ask first and took it from there.
Update: That is, regardless of the answer you can get here, they are the copyright holders, and even if you have a trick to get around them, it's safer and easier to ask.
