 #
 # git caching proxy
 
+# Suitable only for exposing to semi-trusted clients: clients are not
+# supposed to be able to take over the server.  However, clients can
+# probably deny service to each other because the current
+# implementation is not very good at handling various out-of-course
+# situations (notably, clients which are too slow).
+
 # usage: run it on some port, and then clone or fetch
 #  "git://<realhost>:<realport>/<real-git-url>[ <options>]"
 # where <real-git-url> is http://<host>/... or git://<host>/...
