Hi, I am using ZRTChat. This product, though very simple, really seems to work well. I've cleaned up the interface, and it may be viable in production. The only undesirable feature that I can see is that it fills up the ZODB with chat, that is, logs all chat messages internally to Zope. In a heavy chat situation, this would fill up Zope rather quickly. My question-- ZRTChat stores each chat message in a standard Zope folder object. Would it be possible to replace that folder with some sort of external file product that would allow these messages to be stored externally to Zope? What would that product be? I have used the ExtFile Product, but only to read files that are stored externally. I have no idea if it allows you to write external files. To all potential Zope chat product developers-- things I would like to see in future Zope chat products are threaded dialogs (each user displays as a different color), a list of who is available for chat, and private chat.
