We have done this some weeks ago, we even took the liberty of coding it 
into Robert's TT. In the spirit of open source, we sent our work back to 
him. I see he has now implemented it into the official TT. We also did 
the tweaking on our installation. We have been running this for about 
four weeks on 500 terminals across nine schools. Since we have fibre to 
the schools, and all our servers are centrally placed at City Hall, I 
can now remote control students desktops and guide them without leaving 
my office. Very useful indeed!

We also did replace libgcc_s.so.1, like the wiki said. We did not keep a 
backup of the old file. What kind of problems should this cause? The 
reason I ask, is that we have been running this for several weeks, with 
a TT version like the one Robert is releasing now. We have not noticed 
anything out of the ordinary.
