This site has New Chinese Version (NCV), Chinese Uniion Version (CUV), and other English version. Notably, copyrighted ESV, NKJV, RSV and NRSV are there too. Good for doing parallel study. Simple and effective interface. http://christian.net/websword/
However, NCV and CUV has mistakes in characters, e.g. Jame 5:3
你 們 的 金 銀 都 長 了 鏽 (James 5:3 CUV)
你們的金銀生鏽 (James 5:3a NCV)
It is also a bit annoying in CUV because of the extra space between each character. It must be a simple process to clean this up. I might contact the module owner to rectify it.
This is related to the SWORD project at http://www.crosswire.org/index.jsp. I like the MacSword project on the Mac side, simple interface and good for my searching needs on my iBook G3. The parallel layout is so neat and nice.
