Yea, you could do it. In the simplest case, you could build a login form (e.g. winforms) in code in your script and use it to get the username and password from the user.

In a more serious use case, you could build your login form and all the login logic in a separate dll, and just call that dll from your scripts.

If you'd like to try this, let me know via email (antonio at querystorm.com), I can help or at least point you in the right direction.

Thanks! Will do.
