I initially thought about OpenID for this but decided it wasn't a good
fit.  I ended up modifying SQLPASPlugin and plone such that 1) the
login form obtains a session cookie value for my "other site(s)" with
jquery and stores that as a hidden field value to be submitted along
with username and password.  2) Modify SQLPASPlugin to store the
cookie value and associate it with the username.  You don't get all of
the plone security, for instance ACL is not stored in the DB (as I
recall), but you should get roles and groups.

I've obviously skipped a lot of details.  What happens if the JQuery
ajax call for a sessionid fails?
