Hierarchical select trought Content taxonomy field and autocomplete widget

Hi all,
Hierarchical select is one of the most useful contr module i ever used!

I'd like use it's feature applied to cck fields, not on dinamically created select dropdown.

For example

I have an hierarchical vocabulary location

level 1 > country
level 2 > - state
level 3 > -- city

i'd create 3 cck taxonomy field with autocomplete widget

country_field
state_field
city_field

tiping USA into country_field the state field should expose the child states defined into hierarchy if exist, for example NY state, so the city_fild as well

At the end i'd be able to save the lineage terms into vocabolary

I'm willing to pay for that features

Regards
