Actually the forums already seem to be programmed to do that. Read and unread post status seems to be stored in the database. I am on a different computer than this morning, and the read/unread status seems to be accurate. This is the standard way to handle new post indicators with database backend forums, such as phpBB and this UBB Threads. The old Intel forum software stored read/unread in cookies, so different computers had different markers.
