Hi Stinkie, I have been looking at a program called ARC+ in the past few weeks.
http://www.arc-techno.com
Go to the video examples to se it in action.
It is as close as you will get to the workflow that SU provides and seems quite reasonable.
Also, the two guys I have been in contact with from arc-tecno have been very good to deal with as well as one of their resellers in teh Netherlands, Stefan.
Have a look at these short videos on Stefans website. http://www.cadez.eu/video/
Audio is a little annoying so turn off the volume if you want.....
Seems very intuitive though!!
