If "I" should have this problem, I will try this:
change hobbit client.sh so it:
- is not trying to contact the hobbit server (so the bb command is not used)
- the message file is saved in a fixed file (so the pid is not appended to it)
- the logfetch can still work if you update the input file manually

make a daemon on the hobbit server:
- that runs every minute
- contacts the hobbit client with ssh and checks for a message file, if a 
message file is found, the content is send to the hobbit server and the file 
is deleted

Or something like this ;)
