printCafe vs. PrintTalk--Waging a PrintWar?

While printCafe has developed its PCX framework for integration, PrintTalk has taken a different approach. The PrintTalk implementation is available free of charge to anyone who wants to download it from its Website, printtalk.org. PrintTalk defines its mission as developing a common and open communications interface among its members' products. Even so, it is quick to clarify that it is not a standards body. Instead, PrintTalk sees itself as an implementation organization.
