Sadly I will have to correct you.. the modified Hildon GTK+ will not transplant well to modern systems and there is a very high likelihood that all apps will have to be modded to run on top of stock GTK+ and Hildon. Stskeeps said once that MaemoPad had to be significantly modded. There is significant amount of work to be done to replicate the Hildon stack. Just look at how much trouble the Mer project had. They even used a Hildon GTK+ (breaking most other gtk stuff and making it stuck at ancient gtk version)
