I'm working on releasing a small piece of useful Perl XS module code to the world... Corosync::CPG. This allows you to use the corosync cluster stack's reliable, ordered multicast messaging bus from within Perl.
I have applied for a PAUSE id and plan on submitting this module to CPAN as well. For now, this is a super-early alpha. It works for me, but the POD documentation is incomplete and there is obviously no warranty.
The terms of this release are the same licensing terms as Perl itself (GPL/Artistic).
