Great suggestion, I'll try that.

Unfortunately not, I will have to wait for the timeout. But that would be
ok, this is supposed to be done only once during IOC initilisation.

I will have to parse tag=value stuff further down the road (see below), so
what I have come up with so far looks like this (searching for a given uid
and parsing for the identifier afterwards):
in "%.1/uid=\$1.*?device-identifier=([-a-z0-9]+)/";

The answers for a full bus look like this (Tinkerforge stuff via a text
proxy, extra newlines between the blocks added manually for posting):

Thanks for the already very usefuls hints!
