Not a dumb question. The links to mesh networking etc seem interesting. It sounds like the insights from descriptive set theory could yield new hardness/impossibility results in computational complexity, distributed algorithms etc.

are there any current or foreseeable practical applications of those results?

the math of infinity isn't very relevant to the finite programs that humans use. Even today's astronomically large computing systems have size approximately equal to 3 compared to infinity.
