I'm not sure about the utility mentioned in that article, but I do recall that the BootCamp drivers had included a read-only driver to allow boot camp to read HFS/HFS+ formatted volumes. I imaging that you can also extract that driver from the Boot Camp Drivers installation package and install just it.
I personally had used MacDrive 8 for a year or so before I tried the Paragon driver. I was so impressed with the Paragon driver performance for me that I upgraded my muti-PC licenses (all 4 of them) to Paragon when they had an offer for a "competitive upgrade". Both Paragon and MacDrive have their issues, but the Paragon driver seemed much more seemlessly integrated into Windows and therefore worked more reliably for me.
