Hello Rick,

I would be quite interested in testing it ! As soon as you have a working
version, please send it to me and I will test it.
The servers I am working on are :
Linux 2.6.22.14-72.fc6 #1 SMP Wed Nov 21 14:10:25 EST 2007 x86_64 x86_64
x86_64 GNU/Linux
for the 64-bit linux

and :
Linux 2.6.20-1.2320.fc5smp #1 SMP Tue Jun 12 19:40:16 EDT 2007 i686 i686
i386 GNU/Linux
for 32-bit linux.
