One of the biggest hurdles to a medieval communist revolution I think is the fact that peasants are just about the opposite of a revolutionary class. There's something about rural life that does not produce revolutionaries and progressive, but rather reactionaries. Only when you have cities with massive populations, thus having created the proletariat, does it become more possible.
Examples like the European Peasant republics aren't really revolutionary in actuality, they merely lacked feudalism because they were too poor and small, but they weren't actively ideologically upholding this, which is clear from how over time even Dithmarschen developed its own nobility from the families of the people who kept increasingly more often getting elected to be judges.
Then again, maybe some maoist can teach me something I don't know about peasants and revolution.
