Is this good or bad? I can see being on the comittee, but core developer status has me wondering.
I see no harm, but benefits. Both SME Server and ClearOS have some strong points. IMHO we can benefit from them and they from us in the true OS spirit.
For instance the samba packages we provide for SME Server 8, to support Windows 7, is a rebuild from the ClearOS package, where they, on the other side, now use the same build infrastructure that SME Server/Contribs.org uses to generate the packages that was setup for contribs.org by Shad.
