[ncolug] Re: Need recommendations

Thanks for the feed-back!  Rob is also a big proponent of VMWare.  THere
is no way we would not consider it.  We are using VBox only because it's
adequate for our current needs.  Once we begin using a network storage
or some self-hosted cloud-like solution we will need something more
advanced.  I'm not too concerned about teaching products as I am about
teaching concepts, so the final product could be something other than
VMWare...
