After reviewing feedback on and off list it seems I have to make a quick 
retreat here and support 10.6, also for pre-release Qt 5. 

For those who are interested, supporting 10.6 involves implementing 
alliterative code paths where we use API introduced in 10.7 int the main code 
path. This is usually not much code, and I would say the majority of effort is 
testing and verifying that Qt still compiles and runs on 10.6. 

I would like to draw the line at 10.6 though, 10.5 will not be supported.
