Kazaa is a Peer2Peer Connection service, sort of like Bit Torrent or more aptly IRC.
The software itself is just a big form of Networking Program, not illegal even slightly; software hosted via this service is done from peoples personal hard disks and not the companies that created the service (infact nothing more than network indexing and the latest builds are on these companies websites).
It clearly states in Kazaa's EULA about using it for illegal practises, unfortunately a few hundred bad eggs ruin a perfectly legimate service for everyone.
The legalities of Source Code are identical to that of a novel. So when you look at code being stolen it has to be in context of plagerism.
Once source is compiled it is technically illegal to then disassemble (learn that word as it is IMPOSSIBLE to decompile code!), which means that technically people shouldn't even be able to steal your code once it is built.
That said the smarts required to understand a complex compiled program such as a Windows 32 EXE in it's entirity is not an easy task even for the most seasoned of ASM developers.
as for the title heading, from what i've heard (C) bends to suit every platform; with a rep like that it's gotta go all the way on the first date
