I have been mucking around with the improved aust post module.
I am a little concerned about security and upgrades though.

When I install the module into the cart it installs older .php modules into the admin area overwriting existing modules. (v1.3.8a)

As these modules are older than my current code, overwriting them makes me wonder if I have opened any security holes by patching back to older code ?

What will I have to do when a new version of ZC comes out ?

The other area I am concerned about is using a 3rd party to interface between my server and the aust post server.

Is this strictly necessary ?

I ask this because if I base my website on the improved model ... will the VCSWEB server be around for the long haul ?

Is the VCSWEB server reliable ?

Thanks for the great job on the mod so far though ....

Cheers
