So I guess people should comment on Thomas' IETF I-D...

I was just surprised that policy seemed to adversely affect the 'ease of
deployment' of a broker service.   I personally would be fine with a /56
for home use.   I do think it's important that ISPs have a common 
reference for sizes to allocate, though inevitably there will be different
offerings (ISPs will look for ways to charge more, as they do by 'selling'
IPv4 addresses today).
