Do you use a cloud, if you do you can upload your show or mp’s to a folder of the cloud and grant him/her access to the folder of the cloud and email the link to the cloud. You would be able to say how long the link would be good for, either indefinately or expire on a particular date. I did that for the person looking for a copy of the Rolling Stone Magazine, I downloaded it for them and then gave them the link for 30 days access.
