Updating the compiler is on my 6.1 list. This doesn’t necessarily mean that it won’t happen until 6.1, it just isn’t necessary to be completed before shipping an initial release of 6.0.
In other words, it is on my short list
This is a project that I would love to see get started. It seems like we could make an open source module that wraps up Eto functionality and exposes it in an easy to use in a ‘pythonic’ way. Docking dialogs specifically are going to be tricky and will require some changes in Rhino first.
