had forgotten to reply also to the list... doing it now:
[cut the part where it was suggested to make package that contains LLVM
Intermediate Representation bitcode rather than CPU specific assembler]

Paul,
What benefit do you see in the overhead of LLVM IR, compared to standard
packages?
John,
Where do you see overhead in the distribution of LLVM IR?
Advantages:
* more space on the hard disks of the servers, because they contains
repositories only for LLVM IR packages rather than one by supported
architectures
* less use of the CPU time of the servers because they don't optimize
code for specific CPUs
* very reduced cost for supporting more architectures, as code is
client-side generated
* faster code on clients with recent CPUs, because code is optimized for
them, and was not in the old way of doing because you had to distribute
for a common base CPU
* CPU specific code generation and optimizations can be done on idle
time of the clients... there is not much idle time of the servers
