Going to be Playing with Grails
I'm really excited about the addition of Hibernate to ColdFusion 9 (and presumable Railo and OpenBD in due time). However, right now, I have a Hibernate shaped hole in my framework (my little "data mapper that could" is great, but, well, it's not Hibernate), so I'm going to have a go at porting a chunk of LightBase (my in-house framework) to Grails.
Whatever I learn I'm hoping to back port to ColdFusion - ideally as part of the Coldbox framework (If Luis, Sana and the rest of the team don't beat me to it), but in the meantime, expect to see a bunch of n00b level articles on Groovy and Grails as I try to document what I'm learning and hopefully create a useful resource for anyone else interested in playing with the Grails framework.
And please keep us posted with your findings!!
