In reply to andretim:
"With that in mind I think there are a few more components that would be interesting to propvide (if they have the rights to them): !Java and CDFS related components."
!Java couldn't be open sourced, though things like the threading module could (it's a bit of an embarrassment, though - it was a proof-of-concept hack I knocked together in a weekend that was always supposed to be rewritten, but never did).
However, from a legal point of view, with suitable (free) licenses available from Sun, and if Castle/ROO were willing, it'd technically be possible to share the source with specific named individuals, if they were willing to develop it - but the end product would have to be free, otherwise you'd end up having to pay a large licence fee to Sun.
I considered this in '99, but it was too much effort. You'd not believe how much work passing the validation suite is. I took out a licence in my name (with E14's permission), which I suspect is still valid.
