Exactly! You and I seem to be on the same level here...
The medium not only has to have some criterion on which memes to
adopt but also it should be motivated, in general, to adopt
memes in the first place!
I believe that in biological `machines' this behavior is governed
by the reward path-way in the brain. The RP emits feelings of
satisfaction after the organism has taken actions to increase
the biological fitness it stands for. Copulation, feeding and
fleeing for danger are such actions aiming to increase either
fitness of its genes directly or its own personal fitness
If such behaviors were not rewarded the organism would not be
propelled to engage in the mentioned activities and
repetition of them would be absent (reinforcement).
In humans things are a little more complicated as we have
culture to deal with as well. Cultural activities were
rewarded ever since they proved to increase survival. That is,
hunting skills, agricultural memes, food processing memes
all originally served to increase personal fitness.
Hence the reward center had an
interest to reward cultural activities as well. Ever since
memetic activity was rewarded, culture took off.
It even follows logically that the RP carries
both biological evolution and cultural evolution.
To have some sort of cultural evolution in machines, they have
to be equiped with a similar kind of reward mechanism too.
If not, the machines would remain inactive as there is no impetus
to do anything let alone use their valuable resources
on spawning memes.

If resources to machines (e.g. electrical power, band-width)
are scarce, analogous to biological
evolution competition for it will be inevitable as the most
eager and powerful machines will try to grab hold of them.
Memetic evolution in machines will be kicked off then. The
possibility of machines forming alliances to obtain more
resources is not unthinkable indeed, as formation of social
groups is quite common in the animal kingdom.
