Let me know if anyone is interested in taking a look.
From my README file:
bitc is a thin SPV bitcoin client.
- 100% C code,
- support for linux and mac platforms,
- console based: uses ncurses,
- home grown async network i/o stack,
- home grown poll loop,
- home grown bitcoin engine,
- multi-threaded,
- valgrind clean.
