The spam alert alarms went off first but having found the document on the website the method described sounds very interesting. Its the PDF document on the left of the web page.
In brief, the method is to protect a small number of cells on a normal frame of open brood and kill off all the rest of the brood by dusting it with flour, which bungs up the larva.
The remaining cells then have the lower part of the cell wall cut back to the base and the bees will then respond and treat these as queen cells.
It is a bit like the Miller method but the comb is not cut into a zig-zag, trimming back the cells achieves the same end.
