Does there exist a SPV-client in another language than Java? The only (active) project I know that implements a full SPV client is BitcoinJ, which is written in Java. 

Does somebody know if there are any SPV implementations in other languages (like C) too?
I'm writing a BitcoinJ port for .NET (C#, Visual Basic, etc), but since I'm doing it on my free time, it's nowhere near complete.

Other way to use BitcoinJ in .NET is through IKVM (which I didn't use due to some limitations).

I don't know about other languages, but I hope this is helpful.
