"CPython"

[Avi Gross]

David,
I understand now. As a project for your own edification I can understand it, albeit it is a more substantial effort than many people might choose, LOL!
So unless it starts being used heavily and adopted by some organization, the result of your effort will not necessarily be compatible with many modules now available or keep up with changes as python adds features or fixes bugs.
I am curious about why something like numpy could not be integrated into what you do. Of course, if you are the only user, ...
My hobbies to spend my time may not be as ambitious, but are quite a bit more varied! LOL!

The main motivation for a Python virtual machine in Rust is to strengthen my knowledge with Rust which currently has some gnarly bits to it but otherwise is an impressive low level language.   Rust's future is looking very bright as even Linus Torvalds agrees with most of its design choices and is allowing it to be used as a linux kernel module language.   
Skipping ahead to the subject of names, Rython was chosen because "Python" is trademarked by the PSF so anything with the complete word Python in it is out.   A close runner up would have been Camelot but that is already taken.
Going backward to the issue of use and audience.  Making Rython a real virtual machine that passes the CPython unit-tests is the only goal.   I am actively following the faster CPython fork that Mike Shannon, GVR, and others are working on with the intention to try and incorporate what they discover into my project but I don't think Rython will be dramatically faster than Cpython because I am going to implement the same PyObject reference counting garbage collector and unless faster CPython creates a JIT component, Rython won't have one either.  Additionally Ryhon won't have the must have killer libraries like numpy so it's a moot point if my project turns out to be dramatically faster.
To sum things up, I've been retired for over a decade so I have plenty of free time.   Initially I thought I might invest time into becoming a core python developer but looking into it further, all I will say is that doesn't feel like a very appealing use of my time.

David,
I am curious why you are undertaking the effort to take a language already decades old and showing signs of being a tad rusty into a language that suggests further oxidation.
More seriously, I am interested in what this can gain and the intended user base. I studied Rust for a while and it has it's features but have had no opportunity to use it. Is it expected to make a faster version of Python, or enable better connections to libraries and so on? 
What I mean is that if you are planning on making it pass all tests for python functionality, are you also adding unique features or ... ?
My preference is to have names that fully include what they are about. So the name "python" would be left intact rather than mangled, even if the name itself happens to be totally meaningless. So may I suggest something like """rustic-python""" ?

I am at the pre planning stages of making a Rust implementation of the
Python virtual machine and to avoid ambiguity I've been working with Rython
as the name.  I tried looking for a Monty Python themed name but the good
ones seem to be taken.

Otherwise as for a timeline, solo I figure it's going to take me a couple
years to get something that actually passes cpython's python unit-tests.
