It concerns me a little about the Devanagari font not working  
properly, but I'll check that out when I have time.

But I'm confused about what you're trying to do with your \dev commands.
Are you trying to write "\dev{some Latin text}" and have the output  
come out in Lucida Grande? If so, that's (kind of) impossible, and  
you'd need to create your own font that contains both Sanskrit and  
Lucida letters at the appropriate glyph locations. Otherwise, you  
need to explicitly mark up which parts of your text is to use Latin  
letters, and which parts use Sanskrit letters.

Good luck,
