[ale] Simple Linux/LAMP shared contact system reccomendations?

[meuon at geeklabs.com (Mike Harrison)]

   I need a simple effective way for three sales droids
   to share contact info and notes for a couple of thousand
   contacts.

   Yeah, I could write it, but I'd rather not..
   and I don't think we need "SalesForce.com".. Yet.

   Any reccomended, web based, preferably LAMP systems anyone
   used they would like to reccomend?
