Qi-Hardware logo: keep-out areas

The next thing to consider is whether we should recommend (*) any
areas that should be kept clear from other items around the logo.
And if yes, how they should be defined.
(*) The Qi-Hardware logo isn't a registred trademark, so all we can
do here is give recommendations and guidelines for what we
consider good use. Anyone is free to follow, ignore, or ridicule
There's much more to borders than just a distance. I've illustrated
a few parameters here:
First, with start with what I called the "Equidistant rectangle
from the extents": a simple rectangle, parallel to the x/y axis,
and a certain minimum distance (5 basic units in this example) from
any point on the logo.
Going to the left, we could of course use a different basic shape
from which we calculate the distance. Given that the logo has a
very off-balance center of gravity, we could for example reduce
the part of the rectangle around the "foot". I called this "from
[a] derived shape", because it is derived in some way from the
actual shape of the logo.
Of course, it doesn't have to be a rectangle. i've illustrated this
with a circle.
Now the bottom row. We take again the logo's outline as a
reference. This time,the outline "hugs" the logo closer than
before. Now we can calculate the area that would correspond to the
"territorial" waters if this was a country.
We can vary the geometry. Euclidian is the most natural but the
rounded corners may be inconvenient. Manhattan  distance yields
straight lines. If we use Chebyshev distance  instead, we even
get only right angles.
Note that "Chebishev territorial" is concave. If we don't want to
put other things into the logo's white space, we can make the
border a little more convex. Note that it's still concave around the
foot. If we were to eliminate this as well, we'd return to a
Finally, a concave geometry could still accommodate an "enclave".
E.g., for a sub-project's logo, something that modifies or amends
the Qi-Hardware logo (such as a license logo/name), etc.
So, do we want to recommend any keep-out areas ? And if yes, what
should they be like ?
