deniska, I'm using
http://glockdancers.com/mapthis/ as a source to feed a local cache (depending on a page with links to the .zip files and the _county_borders files). Let me know if this setup is ok with you (I will distribute with the cache filled and an assumption that anything already in the local cache is final and does not need updating).
A couple of things before I post the app:
(1)
Regarding this:
NOTE:
In theory, 2 or more counties can share area with same zipcode(s), ie you may get the same zipcode filename in 2 different county zipfiles. In this case you'll have to merge the zipcode files with a same name and sort the data inside of them alphabetically by street name.
This does not seem to be the case (eg. 02068.zip 99704 and 02090.zip 99704 are the same)
Could you give me a case where this is not so. To confirm that I do have to deal with both scenarios (where zipcode files are the same and also where they are partial).
(2)
zip.txt does not have entries for every zipcode, eg:
07086,40769504,-74021890, ,,3472,69785
(7th in Manhattan one you posted)

Here goes nothing:

Until deniska confirm this as working, and all the pre-processed files are there, this is experimental and probably not ready for use.
