Problems with peer example

sorry for my late response.
I fixed the peer example in the release-0.8.x branch:
http://trac.e-technik.uni-rostock.de/projects/ws4d-gsoap/changeset/451
It only shows a device and that it can do discovery at the same time. So
it is more like a proof of concept than a good example. In the trunk
there is a better example with some more "infra structure" (service and
device trackers) that is not included in the release-0.8.x branch.
Be aware that the callbacks in the acc_device are blocking the message
processing loop. So you should built a mechanism that defers these
events as i did with the service and device trackers.
Regards,
Elmar
