Hmm - I haven't really administered Nomachine myself (we have an enterprise installation on one of the clusters at work), so I can't really help you there unfortunately, but only to say that it doesn't often crash or hang for me, and the delay is quite low enough over wan that using the GUI / mouse works almost perfectly, both on OSX and windows.
