I am thinking this package should include the Zend Lib files ...

I am thinking this package should include the Zend Lib files and a note that this is using the psftp executable from putty. I like the idea of what the author is doing. However, I think the author should structure the class in such a way that it can be easily extended to add other options such as ftp or sftp type connections and different output types.

Thanks for the question.

I'm not sure what you mean by including the Zend Lib files. In the example script, it states that you need to have a few things configured; the Zend framework and Putty. I would think that this would imply that you would be using the Zend Lib files and psftp.exe to perform SFTP/FTP operations. If the port setting is set to 21 (instead of the default 22), then FTP will occur instead of SFTP.

As for the different output types, I chose XML because it is easily consumed by many different platforms (ie. PHP, Flex/Flash, Python, etc.). I wanted to keep the size of the package to a minimum.
