A few points jump out at me

- There is no discussion about license. This must be documented and be okay.

- There are no clear changeset tags listed, although there are references
  to tags and changesets in multiple places

> The deadline for any suggestions on the following mailing lists are 
> Thursday 13. February

This misstates the situation somewhat - the imports@ step is a consultation,

just like with the local community. The import needs to be acceptable to 
both and concerns need to be addressed. It's also not possible to say in
advance how long this will take, as it depends what concerns are brought
up and how long it takes to address them.

If a user has decided to map an address on a building way it would be 
inappropriate to remove that user-contributed information.

You should not be deleting existing addresses without a survey to verify 
that they are incorrect.

> unique id to identify the house number

What is the purpose of this tag? How do you intend to use it?

I had a brief look at martello_new.zip

- It doesn't seem to agree with what the wiki page says about addr:full,
  addr:country, or the OSM tags used

- I had a look at the positional accuracy of the addresses, based on Bing,
  after allowing for shifted imagery. The positional accuracy is reasonable,
  but like most sources, not good enough to tell where the front door is.
