You are better off using a cron job (or similar) on the client side, 
getting the client to hit the web server for the code at regular 
intervals, and if code is ready, execute. If code isn't ready, wait for 
the next interval. Use https for security and have a shared secret 
message to identify legitimate clients.

If you try to push code the other way, you will need a perpetual socket 
open on the client side, making the client the server.
