I just confirmed that mozilla does. E.g. mozilla http://bbc.com & sleep 3; mozilla -remote "openurl(http://cnn.com)" happily switches the running session from the BBC to CNN.
That's not running multiple executables: that is remote-controlling an existing one. Not only that, the second command takes over any existing mozilla on the display, even one running on a completely different machine (e.g. a session on a remote Solaris box). It's the last part that is fatal to the earlier help.start/help scheme. For me, on Linux, both Mozilla 1.1 and Netscape 7.0 refuse to allow me to run a new copy if one is already running. This is an issue as the help.start/help interface tries to run a new copy if running R remotely. They do allow multiple invocations under Windows and seem only to run one copy. Try mozilla http://bbc.com & sleep 20; mozilla http://cnn.com. I get a dialog box telling me a copy is already running under my profile and refusing to allow me to run another one.
This works for me! I get two distinct ;frames'. And "pstree -p" shows only one main process with one child which has four other child processes. So it looks as if they are sharing. [ some more snooping ] Indeed. Once I start the 2nd one, ps show mozilla-remote as a parallel process. This then seems to migrate into the earlier mozilla even when that one was started in a different shell. File->Quit also brings both frames to an end. mozilla-1.0.0 as in Debian testing. Dirk
