Wanting to start packaging

Hi all, Having read the thread about packaging on the main list, I figure it's something I can turn my hand to. I have a few queries though... A - Is there a system for making sure there aren't multiple (possibly conflicting) rpms of the same app? B - Is space available for uploading the rpms, or do we need to sort that out ourselves?
