Din p\u0103cate, din cauza multor cauze istorice \u0219i politice, utilizarea hub-urilor NMDC ca baz\u0103 pentru conexiuni inter-client este dificil\u0103 sau chiar imposibil\u0103. Folosind un hub NMDC, va trebui s\u0103 renun\u021ba\u021bi la conectarea la o parte din utilizatori, dar ob\u021bine\u021bi securitate \u2013 f\u0103r\u0103 garan\u021bii.<\/p>\n
