Good article. These look like very useful features, and it's good to see ongoing development.
In common with other posters, though, I'm worried about ROL's own presentation of its products. The website hardly inspires confidence (compare with, e.g., ROOL or MW Software). The other thing ROOL has going for it is an active and highly visible project to port to newer hardware.
It's a real shame we have to choose. RO6 looks very polished and nice, whereas RO5 has a clearer and more visible development plan (IMO).
