E-Mail has too many restrictions on size, spam, etc.

Use a file server (YouTube, Photobucket, Flicker, MyTube) there are dozens on dozens if you look outside the English speaking confines.

Make your file unique (numbers and letters) - LOCK IT.

Send your friend - in an e-mail - the unique KEY to unlock the file.

Change the password after acknowledgment. (Give them 2 hours after the automatic Open-Responce) .... if they did not download ... they would rather watch Television.

Sincerely,
Gargaoyle
