Here is another tool that can be used from a web page. It shows any given passage in 7 different translations
(World English Bible, American Standard Version, Bible in Basic English, Darby’s Translation, King James Version, Webster’s Bible, and Young’s Literal Translation), with further links to 10 additional (copyrighted) versions. You just have to use the format http://bible.cc/book/chapter-verse.htm and voila! Here is an example from John 1:1. Unfortunately, you can only point to a single verse at a time.
