10mW ERP on 8m WSPR without a licence?

Today alone, I have had several reports on 10m WSPR that suggest 10mW ERP at ranges around 3000km would be copied.  

I am convinced following emails from OFCOM that, as long as ISM rules are carefully followed, a licence is NOT needed to run a beacon in the 40.66-40.70 MHz ISM band in the UK. This could well be true in other countries too. In the UK this means 10mW ERP.   It is my firm belief that such beacons, would be received at great range. It is a great pity more people are not trying this.

This is NOT the Amateur Radio Service. It is ISM.
