Was it Alan Flatman who had access to actual test data, or was someone else going to look for it?

Removing my chairman's cap for a moment and expressing my personal opinions:

1) I am not intent on supporting outside wiring and I did not see anyone at the meeting who was pushing it (I may have missed though I was present 99.9%).  As such I would say the PHYs of EFM will not get consideration.

Works for me.

2) If anything that is being suggested means my equipment can no longer push it as SELV, I am against it.  I do not believe that the voltages, amperages or wattages that have been proposed push us beyond (or even close to) surpassing SELV.

Again, works for me.
We need to add IEC 60950-1 to the list

3) No one can anticipate every bad installation practice and correct for it in a specification.  Had the installer who tie wrapped the CAT5e cables to the steam pipe tied them the to the furnace stove piping they would have combusted with or without power.  I would not say bury our heads in the sand; but, the idiots often prove too resourceful to be thwarted at every turn.

We are in violent agreement.
