Really impressive work (I havn't checked details but I have no doubt it works as described)!
I'm sorry I haven't been very responsive lately but life got in the way... Regarding Serf, and this should probably be asked on d...@serf.apache.org instead but since Serf is an important dependency for us here goes: Are you building against Serf 1.3 (only scons), 1.4 (has both scons and cmake) or trunk (has both scons and cmake)? Any changes you'd want to add there? Kind regards, Daniel
