The goals of this library are a little bit more focused on WPF. From the points you mentioned, collection support is definitely in the plans and should come soon-ish :)
For WinForms you can host WPF inside WinForms with the ElementHost (see
http://msdn.microsoft.com/en-us/library/ms742215.aspx). On the other hand, for other platforms you should look to
OpenZoom, which aims to target as many platforms as possible (starting with Flash).
If you want to contribute feel free to do so!
Thanks for your feedback!
