Then you've gotta make a choice.  Personally, mine'd be for the one that 
*overall* works better.  If you're running into an Adobe Flash issue, 
then yup, that's Adobe.  Apparently they decided not to support sound 
servers, only kernel modules directly.

Another option might be to install K12LTSP 5EL without the stock LTSP 
4.2 (but with the edu apps), and then install LTSP 5 from upstream 
www.ltsp.org.  This way you get LTSP 5 with the stability of CentOS.  I 
know that Warren might not like that idea, but you've got to get a 
system up and running and keep those teachers happy *now*.  Otherwise, 
they'll whine about "it works with Windows!" and our cause will be lost.
