Zipped Daisy book and password protected url support

We are currently developing a java application to distribute a daily newspaper in daisy through email. We would like to compress all the generated html files into one .zip file and mail this sinlge zipfile to our customers. The problem with this approach is that the customer must have an unzip tool installed and unzip the recieved zip file each day. Are there any plans for developing a Amis feature to open zip files (with a Daisy book it) directly through the "file open..." dialog? A second option for us would be publishing the daisy book onto a webserver and email an url to open the paper. The problem for us with this approach is that Amis doesn't support urls that are password protected (via .htaccess file). Are there any development plans for that feature? Many thanks
