Maybe there is something I'm missing about your question, but it is my understanding that actual fonts are provided by the client operating system and it's browser(s), using your html and/or CSS as a guide, and I don't believe many O/S's will allow you to cause them to be uploaded because of the potential for abuse.
One work around however is to use php's GD modules to turn the text into an image (using your font) and cause that image to be displayed. Disadvantages would be processing time to generate the image (you wouldn't want to do this with each page fetch unless there was some overriding reason like changing text). Another disadvantage is that the image contents will NOT be scanned by search engines to index the text contained in it (some may scan alt text).
Hope this helps,
