On RISC OS 5 pictured running on ARM Cortex-A8 kit:

I still don't see why that is necessary. The FPA uses coprocessors 1 and 2, VFP uses 10 and 11. Where's the clash?

The main problem I see for using VFP for speeding up FPEmulator is that the FPEmulator works in extended precision. But it doesn't really matter as FPEmulator is for compatibility, not speed.

On RISC OS 5 pictured running on ARM Cortex-A8 kit:

The instruction spaces don't overlap as far as I'm aware. If they did the FPEmulator wouldn't work any more and lots of software would break.

The only necessary change to RISC OS that I can think of would be to preserve the VFP registers on task switches.

There is a problem with the endianness of stored double precision numbers differing between the FPA and VFP, so there are potentially linking issues there I think.

No, I just don't obsess about ads, so don't bother to block them. If I did, I could block them on Facebook too. There are many reasons not to use Facebook (privacy issues, waste of time, nothing on it seems to work properly), but advertising don't seem to me to be a good one.

I spy a couple of integrated ads directly below this text entry box. Going to stop using Drobe now?

On Using shared source to brighten up the desktop:

What's wrong with grey anyway? I haven't seen a theme less worse than the NewLook theme so far. But then, I have Windows XP in " Windows Classic style". It's not what it looks like that's important, but what it can do.
