Got to wonder whether it’s something like ncipher/Thales due to the van someren/aleph1 connection.

Don't know, but there was a mysterious entity that nearly bought the rump of Acorn IIRC to keep producing RiscPCs. Due to some fumble the deal fell through. I vaguely remember it being some kind of media-tech company. Probably the same mysterious entity.

I'm guessing Eidos's Optima video editing system? That was the last of the major RISC OS users as I remember it.
