Why? And why 4.8? The 5.x branch is a far better version of Qt. This looks ridiculous. Qt is a massive framework - the work of hundreds, if not thousands, of people - and this seems to be the work of a random dev with zero backing and a 2004-style website with zero content (everything, even the 14-forum completely empty phpbb forum).
The lack of a public repo of some kind and obvious licensing makes this a no-start for me.
Legal info is also available. http://www.copperspice.com/docs/cs_overview/legal.html
So it's just not in github-esque hosted format you're expecting.
