The Demos in Forge projects take up a TON of SUs/AOs. But if you delete the demos after installing, the next time you upgrade the component you get the demo code again.
Solution: have the component author upload a demo (OAP, OML, or OSP) separately from the component itself (OAP, OML, OSP, or XIF). Then allow the Forge user a choice of "Download Component Only" or "Download Component + Demo".
To make this better, add a "Project" that is similar to an OSP, but can contain Applications as well. That way, the Demo can be a separate Application from the Component, and they can be delivered together in one download. A level above "Application" has been requested a few times already.
