You can't protect any binary from being reversed either. The CPU has
to execute it. The antivirus and antimalware people reverse stuff all
the time[1].
There are only a few good reasons to obfuscate the python code:
1) Embarassing/bad/evil code/comments.
2) you're in the US or similar and want to also add DRM so you
qualify for DMCA protection (I personally am against the DMCA laws).
But what is your end objective? If it's to make money, most paying
customers aren't going to look. Competitors could learn stuff, but
they can't copy stuff exactly or they'd break copyright laws. They
could copy ideas, but cool ideas are a dime a dozen, the difficult
parts are elsewhere. Marketing, execution, polish. Even artwork and
design can be more important, customers are more likely to buy a
product that looks beautiful on the outside with ugly code inside,
than one with ugly artwork but beautiful code.
Apple weren't the first company to come up with a touchscreen phone
or tablet. McDonalds weren't the first company to sell burgers, nor
do they sell the best burgers, even in the "fast food burger" category.
Starbucks is one of the pioneers in overpriced coffee. I don't think
being first or not has anything to do with their success.

[1] Easier nowadays with virtual machine technology. The difficulty
for them would be if a trojan contained innocuous code, but fetched
commands from a server that are OK but could one day be evil. That
said I wonder how well they'd do against polymorphic perl viruses ;).

1) how serious this problem is in your opinion? is it really true that
it is impossible to protect the binaries from reversing?
2) how efficient are the reversing tools on Python binaries now? would
be great if somebody can share some experiences on using those tools.
3) if it is true that it is quite trivial to reverse the Python
binaries, how are you currently protecting your binaries? perhaps with
some obfuscated tools, making it much harder to reverse?
please share your ideas. thanks so much,
Jun
