For me this looks like regression, sorry. I suppose we should find better way to do this. I've used to meet more or less same (as far as I can suppose) problem when reworking code in interface.cpp to make it use exceptions instead a lot of copies of status vector. But it was required to return server's errors from one place (where it's received from network). Throwing such errors after receiving from server was almost impossible, cause this is not an error condition for remote client, and it's normal control flow should not be interrupted - that is why that errors are almost like warnings for remote client. As the result we still have a status vector parameter in a number of remote client functions, but all errors/warnings raised in remote client itself are thrown to the client in C++ style. It's hard to suggest something not seeing the code. Can you send me some fragments helping to better understand what do you want to do?
