The LPI exams - are they more like MCSE (as in Sys Admin / Config) certifications ??

Rather than "development" as such ??    Or are there C & C++ exams for Linux ??

What's the deal with Kylix ?  I heard some hype a while ago - about developing on Linux
 
Just wondering what sort of app's you might build - and whether there's some ADO.NET equivalent...   (or would you use ODBC ?)

I just haven't really used Linux - I could count on one hand the number of times I've even seen Linux.
