If your SE Presentation is too large to send via e-mail, you can give CU's web files service a try:
<http://www.colorado.edu/its/webfiles/index.html>
All you need is your identikey and password and you gain access to 100 MB of storage. Upload your presentation there and then set the permissions on the file such that I can download it. (Test it out yourself before sending me the link. Remember, you need to be able to download the file WITHOUT logging in.)
