Feature request - exception serialization

[billy]

It see the comm layer cannot serialize the exception throw from the
service it invoked, currently only a 500 generic error would throw to
client, it would be nice to have if it can also serialize custom
exception from the services.
This would be great for integration test of the server code.

Hi Billy -
I'll make note of this and hopefully if it is not complex to add, I
can include it in next release.
