You can do it by executing a system script (i.e. bash) in the
background. But you have to have privileges to do it, which are not
normally possible on shared hosting.

What's the problem with just downloading the file? Users are used to
downloading big files (some I've had to get are > 1.8GB GPS maps).

Additionally, it might be ok for your system to send a huge file - but
may NOT be ok for the user's mail server to ACCEPT a big file.
