Depends on how much WDSc is in RDi I suppose.There's almost no WDSC in RDi. It's just Eclipse plus RSE/LPEX plus the application diagrammer, with a preview of the screen designer. I hope that the two new pieces, application diagrammer and screen designer, are not Windows-bound. And the RSE is being open sourced, so that should soon not be an issue. What's left is the editors, and while I love the functionality of the LPEX editors, having them be Windows-dependent is a big issue long-term.
