bluenose>"Castle state they maybe willing to sale RISCOS IPR if the price is right "
Read carefully what nijinsky wrote above. If Castle did sell the IPR it could do so to *any* organisation (they *don't* have to sell to ROL, and perhaps the next owner will require more onerous terms from ROL). Personally I hope they *don't* sell it off - they've updated RO5 several times - and have been very open with their documentation (have a look at ROL Select for a contrast to that).
Let's suppose Castle simply did stop making machines and sold the IPR to ROL (and it took say the next 2 years worth of Select subscriptions to pay for it). What then? You'd have the A9Home as your top end machine (not a particularly appealing prospect eh?). Development would grind to a halt (2 years worth of Select subscriptions remember spent *only* on a license- so ROL in that case won't be employing anyone to do development for quite a while).
The more appealing alternative is that Ad6 license whatever they need to license off Castle... ROL's Select still trundles on picking up a subscription here or there (with the money raised going on development rather than buying out the head license)... and Castle have a little more money that may induce them to improve on the Iyonix or even (gasp) develope a new machine.
Or people could just be silly - hound Castle out of the market, have ROL use up all its money "buying a license" and have Ad6 selling a very limited machine to a declining market in which that machine is the last RISC OS one there'll ever be.....
