First, a couple of pointers:
Albireo proposal: http://www.eclipse.org/proposals/albireo/
Wiki page: http://wiki.eclipse.org/Albireo_Project
The wiki page has very little content today, but it will grow over time.
Add it to your watchlist if you are interested in this proposed project.
The existing proposal lists a some specific features for Albireo, but
it's not meant to be exhaustive.
We'd love to hear about what you are doing with Swing/SWT integration.
What are the problems you have faced? Were you able to solve them? If
so, how? In general, what would you like to see a project like Albireo
provide?
In any case we'd like to know if you support this project, either here
or via e-mail. (Better still, how about participating? :-))
This information will help us validate and improve the proposal, and
hopefully help make the project something that is useful to a wide
audience.
