There are several reasons why this is not standard:

  *  opening a connection is expensive
     you may not want it for each user.

     Note that connections are thread-local objects.
     Therefore, each thread will have such a connectioon
     (at least in the worst case).

  *  It is unclear when a user logs out (he may never do this
     explicitely; just switches off the computer, logs in again

I fear so: an External Method or a Python Product.
