PyPy can generate code which is comparable to compiled C in speed. 
Perhaps you mean, "if execution speed is the most important thing, using 
a naive Python interpreter may not be fast enough".

Security by obscurity.

Nevertheless, although security by obscurity is ineffective[1], Python 
supports it. You can ship only the .pyc files. For added obscurity, you 
could put the .pyc files in a .zip file and ship that. For even more 
obscurity, you could write a custom importer, and then ship your python 
byte-code hidden in a mp3 or TIFF file.




[1] Shipping only compiled executables hasn't made Windows any more 
secure, prevented viruses and malware from taking advantage of zero-day 
exploits, or prevented software piracy.
