Very cool, glad you're doing this!

I think we need more context from you, more specifics about what you
want to see happen.

Here's a preliminary answer: only a client application (i.e. the user
of libsvn_client) is allowed to interact with the user directly and
use stdout/stdin. Up till now, this has been extremely rare.
libsvn_client has defined specific callbacks for this. For example, a
client application has to provide a function of type
"svn_client_prompt_t" so that libsvn_client is able to ask users for
names/passwords whenever neon receives a challenge. I'm guessing you
would want to define more callbacks like this.

Also, you might want to investigate if your changes tie into a larger
project -- the creation of libsvn_auth. gstein has a Grand Plan to
move all our auth code in there and make it very pretty. He can talk
more about that. Right now, that library is just a hollow shell.
