Can multiple machines running the ODBC-ODBC Bridge client simultaneously use the same ODBC-ODBC Bridge server?

Yes. The Easysoft ODBC-ODBC Bridge server can handle multiple simultaneous connections. The ODBC-ODBC Bridge server accepts a connection, hands it off to a thread or process to deal with that connection, and then immediately goes back to accepting new connections. An ODBC-ODBC Bridge server can therefore handle connections from many different client machines at the same time.
