As I researched this conflict I was amazed not only with the scale of this seemingly obscure revolt but also of its significance to the plight of the Jewish people for over two millennium - like you said it planted the seeds of many of the future conflicts in the region. This is a quote from Wikipedia that I think describes the significance of the conflict:
"Modern historians have come to view the Bar-Kokhba Revolt as being of decisive historic importance. The massive destruction and loss of life occasioned by the revolt has led some scholars to date the beginning of the Jewish diaspora from this date. They note that, unlike the aftermath of the First Jewish-Roman War chronicled by Josephus, the majority of the Jewish population of Judea was either killed, exiled, or sold into slavery after the Bar-Kokhba Revolt, and Jewish religious and political authority was suppressed far more brutally. After the revolt the Jewish religious center shifted to the Babylonian Jewish community and its scholars. Judea would not be a center of Jewish religious, cultural, or political life again until the modern era, though Jews continued to live there and important religious developments still occurred there."
Little facts about the conflict amaze me too - like how the Jews used the caves as hiding places and storehouses very much like the Palestinians are using them today to hide and tunnel out of Gaza and even to conduct raids in Israel. It is forcing the Israelis to scour out the tunnels much like the Romans had to against the Israeli's ancestors.
