The current releases of Seam are ridiculously large, weighing in at around 80MB. That is almost as big as the JBoss AS download! While it is critical to offer the entire bundle for Seam developers, contributors, and source builders, I think it would be appropriate to offer a "bin" distribution that is intended just to run Seam. Perhaps just spin off seam-gen as its own download. That should give people exactly what they need to run Seam, and nothing more.
Below is a comparison table of some competing projects:
Spring Framework: 10MB (2.6MB if you pull it from the maven repository)
Ruby on Rails: 2.2 MB (standalone version)
I remember when I first discovered Seam, I put off trying it out because it was too hefty of a download. Let's make it more attractive.
