It was not too bright of IANA to assign 401/TCP (ups) when 3493/TCP (nut) was 
already available, but the problem was probably lack of visibility to IANA of 
3493 (nut) as a UPS management port back in 2008.

Agreed, I said much the same in the I-D Section 7 "ÏANA Considerations".  I 
would like NUT to be able to use "ups", and the names are not a scarce resource.
