But can the interpreter interpret itself?

This was my question as well. I believe the scope of this project is to interpret Python bytecode using Python.

It isn't a LISP :P

I’m going to start having my server send

Then we will see what people say when my stuff is posted :^)

Then again my stuff probably wouldn’t get much attention to begin with.

But if it did...

People would have to admit that they are all living in the present whereas I was living in the future.

There is, however, http://www.aosabook.org/en/pypy.html , which is indeed self-hosting.

Doesn't need to be a Lisp. All kinds of interpreters can interpret themselves if they're written in the same language -- similar to bootstraping a compiler.

Just in case anyone doesn't know, there's actually a real, live project that does this:

https://pypy.org/

(Technically the base interpreter is a subset/restricted version of Python however). The reason this is done (my understanding), is that a the python source code for the base interpreter can be fed into a JIT generator, which produces a Python interpreter that can perform JIT optimizations.
