I must object again that. I use D-Bus on a very small processor (Analog Devices Blackfin BF-537)=20 and it work very well. The library is around 200k on the target: this is=20 very supportable for embedded device, especially when you take in=20 account all the simplifications it allow in the code of each=20 applications. The D-Bus library have very few and simple dependency. D-Bus is a growing standard for the communication between applications.=20 I expect that sooner or later, QEMU will be a D-Bus service.
