I got a note back after the last issue that talked about double checking your backups to make sure they work http://www.antion.com/ezinebackissues2003.htm
Here it is:
One last thought on backing up your presentation on to CDROM. I did a speaking gig this week in Vegas and had to use my backup presentation on CDROM. Low and behold, when I opened the presentation it was barely readable!
It turns out that I had used a non-standard font (balloon), which was not installed on the conference's emergency laptop. So...word to the wise, put any unique font files on your backup CD as well.

Tom says you might also limit yourself to standard fonts.
