I should add something... at least to my knowledge (which is possibly
about a year out of date) there hasn't been explicit and extensive
testing of this exact procedure. However, the very first NDB on Windows
environments were mixed platform ones (some nodes Windows, some Linux)
and there's nothing in the protocols going over the network that should
have anything to do with Windows vs Linux.
But I certainly would say it should all work and would be quite
surprised if it didn't.
