Hi Christian,
Thank you for your opinion, it is much appreciated.
There are similarities but there are also a few important implementation 
differences:

* It is easier to add languages to Bridge than it is to any of the above 
platforms: In order to make Python run on those platforms, those 
projects needed to write a compiler from Python to those platforms' 
respective intermediate languages. That is a very hard task. In Bridge, 
we provide the BECR, which makes it easy to re-use concepts implemented 
in other languages. For example, after we are done adding enough 
concepts to the BECR to compile 100% of Python's features, adding Ruby 
will be relatively easy as there are many similar concepts between the 
two languages.

* Bridge enables Python code to interact with more languages through our 
external interfaces: Bridge code can interact with libraries not 
compiled to Bridge. So Python code will be able to call Swift, 
Objective-C, Java, and C code, to name a few, even if they weren't 
compiled to Bridge.

* Bridge integrates with CPython in order to provide the same experience 
developers are used to: There are many Python modules written in C which 
are not usable in the above platforms. In Bridge you can use any CPython 
module. So when you are creating a Python list in Bridge, you are 
actually using CPython's list implementation.

* Bridge makes Python faster: Python code compiled through Bridge is 
compiled to native code. Because we are leveraging LLVM's many 
optimizations, Python code will run faster than ever.

* Bridge is more hackable: Using plugins, Bridge is much more accessible 
to community participation.

Most importantly, Bridge will enable Python code to run on many new 
platforms (iOS, Android, web browsers..), while none of the above 
platforms provide this ability. We aren't looking to compete with 
CPython, but rather to complement it.
