The SQL thing is not an inherently bad idea, but why /not/ implement the NT 
"hive" format (the random access binary db mentioned above) instead?  This 
might involve some ugly reverse engineering, but I think this would allow 
registries saved out via Reg{Save,Restore}Key to work.... in fact, doesn't 
wine already read this format when using a "Windows" installation?  Some 
months ago I tried to run an application I wrote for my employer, which used 
those API's to import prefabricated chunks of registry stored in this format, 
but it failed to read them in.

I guess this is another "hey, somebody other than me should do a crapload of 
work" type of post... but I thought I'd mention it to remind everyone that 
there is a Windows-API-compatibility justification suggesting that approach.
