Hi Marvin,
Looks interesting. Could you possibly create a little testcase, that shows, how to use it?
I'll try to create a testcase though I'm not sure it can be little

...
Also, it's not clear for me now what the testcase should cover.
Anyway, some investigation is required.
And what about GC-friendliness? Any information about that?
All sendable classes in multiverse implement Marshallable interface. It contains two methods to encode/decode objects from byte buffers. Typically, object decoded into
this and decoding method returns
this. So, no extra instances are created.
