Characteristics of the OpenSER project
listen to your usersbe available on the communication channelsfix bugs and apply patches in time, make it easy to participateorganize community eventsopen projectcontributions are welcomeeven if only a small number of users need themdescisions in public with low overheadget the code outkeep the trunk in a good shapereliable and regular releases, short cyclebe standard compliant and performantbut provide the flexibility to work around broken devices

Comparision of the SER and OpenSER project
why and howinterested in size of the project, community and pace of the developmentonly public visible informations evaluated over one year period (April 2007 to March 2008)Repository activityCommits SER/OpenSER = 45%Changed LOCs SER/OpenSER = 31%Mailinglist ActivityDeveloper List SER/OpenSER = 39%User List SER/OpenSER = 34%Public ReleasesSER = 0 Major, 0 MinorOpenSER = 1 Major, 5 Minor

Scenarios for a consolidation
whyduplication of effort, increasing competition from other projects/ companiesthere is already code flowing from SER to OpenSERsplit of the userbase and developerhow1) merge of OpenSER into SER2) merge of SER and OpenSER into a new project3) merge of SER into OpenSERsuccess chances1) is not reasonable because of different activity levels2) impossible as important developers would oppose3) only meaningful option which has some supportOpenSER is open for contributions
