Hi, hopefully there'll be D-Conf in 2013. Please try to reach out to Distributions (Debian, Fedora, etc) for a panel to find ways of making D and D libraries and applications available in this Distributions.
For Debian the best way for an initial contact would be (I suppose) a mail to pkg-d-de...@lists.alioth.debian.org with an initial CC to debian-de...@lists.debian.org and debian-proj...@lists.debian.org Best regards, Thomas Koch
