If giving a credit in the class comment is enough then this is something different. We do not have to have a mixture of slighty different but not so quite licenses in Pharo. stef On Jul 29, 2011, at 4:59 PM, Torsten Bergmann wrote: > Stef wrote: >> or you should ask a dual licensing.

Yes, apparently if Scratch team only concern to not confuse people with experimental forks and not use scratch logo, then they may state that if you using only parts of project which has nothing to do with it, these parts may be covered by just MIT license.

But a database connection lies above a socket connection and is independent from it. You can send database request over an arbitrary socket connection to the database. This way you can't introduce a security problem. Pooling sockets is more difficult. If things communicating over the socket the authentication might going over that wire and authenticates the connection/socket instead of some abstracted session. In this scenario a socket pool would open a huge security problem giving access randomly to restricted sources. Norbert
