yes

the binary distributions only rule is a consequence of the closed TCK.
the TCK is closed to ensure a revenue stream for the spec leader.

i'll be interested to see whether the JCP survives. sun broke the
basic premise over the harmony TCK (all participants whether open
source or not hold contracts with sun who acts as an independent
judge). given that most open source projects can't afford to sue sun,
the legal framework needs extensive revision. it would be cleaner for
the JCP to issue a license covering any works that pass an open source
TCK for everything except branding rights including the mutual patent
grants. branding rights are only really required for commercial binary
implementations so an additional secret TCK and payment could be
required to unlock those.

trademarks are the important point (bit like firefox)

cool

you'd be surprised :-)

at least one major corporation has taken a derived work based on
harmony codebase through the TCK

and ask yourself if google would have based andriod on harmony unless
it worked...
