The backup feature, which really is only a small part of the overall
featureset, currently operates in one of two modes, TPV compliant mode and
unrestricted mode. MyInventory forces the download component to be TPV
compatible when connecting to any known Linden Labs grid (and similar
protection is underway for other grids), My original mail had two topics.

1) Which grids would like to have the same hardcoded protection level
against unrestricted download as Linden Labs
2) This tool may - if it becomes popular - create a lot of duplicate
assets, therefore I came up with a suggestion on how to alleviate this
problem.

Going closed source is simply "security by obscurity" under a different
name, the "black hatters" already have the ability to take what they want,
claiming that content creators assets are safe is simply not true, and that
fact holds for Linden Labs grids as well.

Even if you decide to block MyInventory, the blocking tools are so
inadequate in these days of fast recycling DHCP servers, that all you will
manage to do is to block out legitimate users, the "black hatters" can
easily get around these limitations. And is that really what you want?
