Hi I am have built an interface(IArchiver) as part of my gsoc project,which is supposed to work on the basis of message queues. I am intending to use the same interface for multiple archives, using separate queues for each archive in this system. So for this I am registering different archivers(say ArchiverA and ArchiverB) in the config(mailman.cfg), with their class parameter being the same. But it has come to my notice, that the Archiver runner while enumerating the archieverset(IListArchiverSet), builds the set based on their class name, i.e. it builds a dictionary where the key is determined by the class of the archiver interface, and not the actual archive. I feel this makes us use a separate interface for each archive, and my design goes against that(my design wants to use the same class for multiple archives). Is there a special reason such a design was chosen, and if my idea seems fine, should I go ahead and make some changes in the mailman core. If so, please provide suggestions on how you would like me to go about it. Thanks Anirudh Dahiya
