[Zope] Q/OT: How to Share Information across Organisations

Although this question is not about Zope per se, I'm sure that Zope offers some good ways of implementing solutions. I have just started creating a web site for the Ontario Suicide Prevention Network, as a volunteer. I have found quite a few organisations that offer information for people who are suffering great distress. However, there appears to be no central list that all organisations might share so that any individual finding one of the sites would be sure to obtain all available information, particularly about telephone distress lines. Would someone please suggest alternative ways of implementing a common list? I have been thinking in terms of providing some kind of RSS feed. How does that sound? Thanks for any help. Bill
