Re: feature request
"In fact, why not make native code run as well, straight over email, it would be super neat."
Outlook used to have that feature, you could embed a sound file in your mail which would then be saved to disk and played... even if it had the extension .exe. (Explanation: The Windows API-Call to play a sound internally maps to the API-call to execute a program. So you could convince Outlook that it's a sound via the MIME-Type, but effectively you could send a native program.)
