I don't mind however you would like to host it.
Regarding your questions about the D3 and the band unlock, there is no NV editing to band unlock the D3 because they changed the may the lock mechanism works and removed it from the NVM and made it inaccessible in the signed radio image. Since only signed radio images can be flashed, they can't be modified.
Fortunately, as you will note in the thread on this forum, there is a band unlocked Chinese radio from the XT883 that can be flashed to the D3 because they are identical hardware and the signatures are accepted. This means that you can run that radio under all of the stock builds available and most of the custom ROMs that I have seen reports about, including ICS builds. You need to use an edited build.prop as well to get the radio properly recognized had configured for GSM use.
Unlocking the SIM is a separate matter and also does not involve the NVM.
So, I am not certain if that answers your questions or not, but the NV edits like those on the original firmware builds for D2G and Pro were considered far too vulnerable to tampering and were changed at the behest of VZW almost immediately after release.
