If it is confidential, you do *not* want to use the session bus. You want to keep everything in the system bus or use a separate data mechanism. As for clipboards, let's not reinvent the wheel. Use two X11 connections instead of transferring the data over D-Bus. -- Thiago Macieira - thiago (AT) macieira.info - thiago (AT) kde.org PGP/GPG: 0x6EF45358; fingerprint: E067 918B B660 DBD1 105C 966C 33F5 F005 6EF4 5358
