Very cool! Just waiting for your ping. :-)

As we discussed at BioHackathon: I just got your point but I have no
idea how to implement that source code shipping model for the
libbiod-dev package. I'm fine with whatever is done with D packaging
in Debian.
To get some numbers: Do you think rinning test/test_suite.sh could
give some impression about the performance gain / loss?
Kind regards
Andreas.
