This code provides a Google App Engine service where you can upload small files via SSL and be given a URL and password for them.

Then, you can email someone the URL for your file and give them the password via some alternate distribution channel and know that as long as only they have the password, only they have the file.

I'm writing this because I need to get my realtor a PDF and I suck at faxing.

Update: drat! It, of course, doesn't work in IE.
