How do I export a Keynote Presentation to PDF while embedding the font It seems like the export to PDF option currently exists on Keynote (version '09) does not embed the font I use.

What are my options besides buying Adobe Acrobat Professional?
I have tested the font you mention in exporting pdf (best quality) from keynote and it is both embedded and displays correctly on my iOS devices using Adobe Reader or iBooks to open the file.  It should work for you as well.  If not, feel free to send me an example of your pdf for testing (tom at bluesky dot org).
