Here is a suggestion for a product.
For years I have been using HTML Guardian from http://www.protware.com which not only does compression of the html and CSS but also encryption of the html, CSS and JavaScript files.
This program is great as you can even encrypt parts of your pages and it has the ability similar to WB to check the encryption with other browser types prior to saving. It will even protect your images on your web site.
Check it out. call it Blumental Guard (cant think of anything else ) tied together with WB it would be a great pair almost a marriage in heaven so to speak
