Pyro looks nice, but it's Python-only. I'd
prefer something that has multiple language
bindings. Also, it's in the same domain
as CORBA: distributed computing. There must
be a stripped-down subset that works better
for simple message-passing between apps running
the same machine. In a portable manner.
Right now, there are some reasonable
systems on different platforms:
- Win32: COM/OLE/ActiveX
- MacOS: AppleScript events
- KDE: DCOP, this has a nice feature-set, it's
lightweight and I'd really like to see a
cross-platform version of this. Right now, it's
tied to Qt (notification is done via the Qt event loop).
- Gnome: CORBA using ORBit
- Generic: XML-RPC, ICE/X-atoms (for X Windows),
various CORBA implementations/clones,
or cook up your own app/platform-specific protocol
on top of sockets or pipes.
I might try to spend some time creating
an abstract framework for inter-app messaging.
Something really dumb and simple, which covers
the common cases. And then have multiple instantiations
of the framework, perhaps one using simple UDP sockets,
or using platform-specific stuff like COM or DCOP.
And have multiple language bindings, with the ultimate
aim of apps being able to do simple messaging in
a portable manner ...
