Interesting.

Any code commonalities with the pidgin skypeweb plugin?

I bet they used a cracked version of IDA too. Kind of sad to see the open culture of reversing violated.

I see absolutely nothing wrong with wanting to profit from this. You're not being forced to use a commercial license, and the LGPL is adequate for most open source use cases.

I haven't spent much time browsing through the source but the code quality and security is pretty dismal so far. Not to mention the confusing project structure.

Magic numbers, ... and strings, all over the place [0]. Memory leak galore (debug code?) [1]. Probably buffer overflows all over the place, here's one I noticed [2]. I suspect others given the proliferation of opaque pointers and memcpy usage.
