I've just discovered the iGlobe project (thanks Patrick!) and am very interested and excited by the possibilities of viewing nD NetCDF in WorldWind. I have a very strong interest in visualizing NetCDF data and am the lead designer/developer for ncWMS, an implementation of the OGC Web Map Service for NetCDF data (http://ncwms.sf.net, if you'll forgive the plug).
In ncWMS we've worked on issues such as rendering images from data in non-lat-lon projections, reading large NetCDF datasets efficiently and a few other things that may be relevant to iGlobe. I'm not sure what problems you're currently wrestling with, but maybe you're coming across some of the same issues, in which case I'd be happy to contribute code and/or expertise. At the same time, I'd love to learn more about iGlobe.
(By the way, can I get a copy of iGlobe from somewhere? Sorry if I've missed an obvious link somewhere!)
