Ah, ok. I am also ignorant about dbus too.
This one helps:

Interesting. Though hard to get hands on dbus with the OS-X I am  
using also:
http://lists.freedesktop.org/archives/dbus/2006-September/005844.html

There is a dbus squeak implementation done by Daniel Faken:
http://www.visoracle.com/squeakfaq/dbus-inter.html
http://lists.freedesktop.org/archives/dbus/2005-May/002673.html
I haven't tried it

I have not found an "application starter service" though this should  
not be too hard to implement - or exists already probably.

But: One cannot directly send messages to other computers via dbus,  
nor does it work for interfacing apps like csound.
So it's a solution to talk to (and maybe start) other applications -  
but not for everything. Grrr, no silver bullet again... ;-)

So, shall the csound experience of Squeak be based on the services  
TamTam already might provide (if it was connected to the bus) or do  
we want/need a direct csound interface?

And: Anyone up for trying the dbus implementation of Daniel in Sugar?

Cheers,

Markus
