Follow-on to Mobile OS item

This item over at Ars Technica caught my attention, especially in light of my last post on this blog. Given the importance of a vibrant ecosystem that includes apps, this software from Palm substantially lowers the barriers to entry for app developers for the WebOS. Using this environment, apps can be constructed by relatively unsophisticated (i.e., without particular programming skills) end users and, if done well, even be monetized. I presume the most successful apps would be professionally re-programmed and optimized. Wouldn't this have strongly positive effects for the ecosystem?
