I have just remembered that something similar happened to pdftex: it 
generated larger files when font expansion was enabled, but according to 
the microtype documentation that was due to the fact that fonts were 
embedded many times. This was improved in a newer version.

AFAIK LuaTeX doesn't embed expanded fonts many times, is there any 
possibity that in the future the font expansion technology in LuaTeX 
will be improved so that LuaTeX would generate smaller files?

Thanks for your help,
