Exactly. I've ported libunwind to work on Android and hacked the 
debuggerd to make use of libunwind-ptrace to dump stack traces. The 
other reason I wanted a libunwind with remote unwinding capabilities 
only is that bionic (Androids libc) doesn't support dl_iterate_phdr 
which would be essential for local unwinding.
