I'd really love to integrate your patches and until my plugins efforts
is not complete we require you to sign a contributory license agreement,
just like MySQL did .
Once my plugins work will be done, we'd go towards a common core under
the GPL, without having to sign the CLA and commercial plugins for our
premium edition. This would:
1) be better and easier for contributors because they can retain all
2) be better for us, not having to maintain two independent branches
of syslog-ng (which is right now about 6 branches: syslog-ng PE,
syslog-ng OSE, syslog-ng Store Box, with 1-3 currently supported
versions from each)
Hopefully I can finish the plugin support in 3.2, but I'd like to
integrate your patches earlier if you are willing to sign the CLA.
 I don't really know what's up with MySQL these days, after being
purchased by Sun and then by Oracle.
