Sun going open source

with everything but Java itself?

I don't know if this is the greatest idea, but their products weren't doing well before they went open- how will then do now? I think the adoption rate won't change drastically. I guess a second question is how will it affect the future quality of these projects. Just because they are free and the source is open, there isn't a community of developers around these things that Sun will be able to leverage (such as the amazing community around Eclipse). So, what do they gain, besides maybe making BEA and IBM drop their prices? My guess is that they won't drop their prices- and now they have some numbers to say that Sun doesn't think there software has instrinsic value, while theirs is worth upwards of $10k/CPU.
