Appcelerator

As you may perhaps have read on the Net, Marc Fleury, founder of JBoss, has joined the board of the Appcelerator company.
This company, of which I have not heard before, is entering the RIA landscape.
I have not yet used their products in detail, but from what I've been able to read on their web site, it looks promising.
It seems the business model will be closed to JBoss one, that is it is based on an open source offer.
In fact, they have to different sites, www.appcelerator.org for the open source package and www.appcelerator.com for the commercial part.
More to come when I will have evaluated the product
