Shouldn't the objectives of ROOL facilitate ROL to produce select for the Iyonix?
Surely the problem must be that it hasn't progressed as far as would be needed?
(Presumably with the disagreements that Castle have had with ROL in the past, they see as intransigence on Castle's part.)
The ROOL initiative seems like it could be the answer to a unified OS model.
As long as ROL and ROOL keep/make the structure of the two RISC OSes compatible, so a working system can be constructed from a mix of components as needed, having two systems needn't be the disaster it could be if aprroached wrongly. (It might even have adavantages).
