Nearly: bash spawn expect and dns-sd

[Andre Garzia]

David,

I, Andre Alves Garzia, Bailiff of Hacks give you the following solution:

for registering: use tempname() to obtain a safe file. Output bash
script into tempfile. Chmod +x tempfile and then execute it.

for listening: same trick as before but redirect all output of the
command to text file such as:

dns-sd -L 'LiveCode Port Mapper'_livecode._udp. . >> mylog.txt 2>&1

then keep a send in time loop reading mylog.txt for new data.
