The PluggableAuthService product is available in CVS:

    http://cvs.zope.org/Products/PluggableAuthService

It depends on the PluginRegistry product:

    http://cvs.zope.org/Products/PluginRegistry

Both are "releasable", but not yet released (I just reminded Zac to cut 
the release tarballs).  PAS has a SessionAuthHelper plugin which should 
serve as a model for the part of your problem which revolves around the 
session;  you would need to write an "authenticator" plugin which 
validated credentials against your web service.

I was referring to using the PluginRegistry, which is a lower-level 
utility, to (re)write the SQLSessions product, which needs to be 
"pluggable" in order to accomodate different backends.  The PIR is a 
Zope 2 analog to the Zope 3 "local utility" service:  it stores a 
perstent map of the plugins registered / activated for a set of 
application-defined plugin interfaces.
