Embed fonts in Keynote?

I am a research scientist and giving visually pleasing presentations is one of the things I love best about my job. I use Keynote for its flexibility and ease, but the inability to embed fonts in my presentations is almost a deal-breaker. I am very particular about the look-and-feel of my presentations and I am thus very picky about typefaces. The last thing I want is to have my beautiful typeface changed if I have to use someone else's computer system for my presentation. Why can't Apple allow font embedding? (Yes, I know you can save your presentation as a PDF with embedded fonts, but that defeats the whole purpose of using Keynote with all of its animation and transition options.)
