Groovy can do anything! Groovy can save the world! I am publicly announcing my intent to look into opening a JSR for WS-ActiveGroovyFX Script.Net 2.0! Not to be confused with WS-ActiveGroovyFX Mobile.Net 2.0!, that one has a REST based interface and no AJAX support but the marketing folk felt that keeping the WS- prefix would provide implicit credibility to the enterprise mobile crowd that carries Black Beries and Treos.
Yea, It's not yet too late for Groovy FX, but it's not too early to mock it either.
