I would also be interested in multiuser ZSQLs, though it's not my main
goal and I don't expect participating on such coding.
Provided there wont be thousands of users (mine number is just about
20), how about to create a pool of connections in some ZODB folder,
simply identified as sqlconn_jack, sqlconn_john, sqlconn_martin, ... and
teach ZSQLMethod to select appropriate connection upon request?
SQL connections currently support auto-connection upon request, so a
timeout disconnection would be nice added feature in this case, but for
small number of users it does not seem to be necessary.
I think this would be a considerable, but easily implemented, step to
obtain SQL userbase binding.
Is there a problem somewhere?
