Contrbutions, modules andPlugins

[Vinicius Carvalho]

Hello there! First I'm sorry about this question, I did not had the proper time for a more in depth search on this subject. Anyway...
We're facing a problem with our software, we're creating modules for it. The basic idea is: if you buy modules A & B, the menus, configuration screens, change displaying new information. All the user needs to do is deploy the new modules (some jars). We're searching jplugin for it, but I found it too immature for production use. So I remember Hivemind (since I'm a Tapestry user).
I was thinking if one could achieve such functionality with Hivemind. Create a base system, and by having modules with new contributions, the system would be customized per client?

Regards and good coding
