Custom fonts - possible for multiple browser application?

Folks,

I am developing a web site for a company that has its own custom designed font, and they are keen to use it!

Is it possible to use a custom font for a web site developed in Domino? The web site must be capable of being browsed using MS Internet Explorer, Firefox and Safari.

I know it is possible to add a custom font to a PC, but this web site will not be within a company firewall, so I have no control over the users’ PCs.

Thanks in advance for any information or pointers,

Jimmy.
