Exactly! The value of any of these pieces of software increases as more
people use it (a network effect). The growth of the "Magma network" is
sharply limited by the high price; the growth of the "Sage network" is
limited by bandwidth and having a fast enough computer.

To give an idea of what sort of limits that "sufficient bandwidth" and
"fast enough computer" impose: I just was in Vietnam for vacation, and
even in rural areas, one finds internet access and computers that are
fast enough to run Sage (though perhaps not terribly well).
