Well.. i would like to help but since i have just a little more then 5
weeks to get this done i really have to use what is the fastest way
for me. in the case of the dbus-c++ api and the dbus c api it's
leaning towards c because i can just follow examples there. If i had 4
months or something to work this all out i would probably invest a lot
more time in the c++ api

for now it seems unlikely that i'm gonna use it.

Also about this school project that i do now. If this project is a
success for my school it might (i said might!) be possible that it's
gonna be a part of the Computer Science lessons which means that about
40 students a year will try this dbus stuff and also might end up in
deciding to use dbus-c++.. and if that is so "beginner friendly" as it
is now then it might scare them off and (like me) also use the dbus c
api...

So for the sake of this project please make it beginner friendly ^_^

Also something that i find strange is that a newly made function is
not automatically assigned to dbus.. surely there must be a way to get
around this and make the dbus-c++ api more user friendly.
