hello Roberto

it should be Moshe who answer it...but I'll take a shot first :-)

As far as I remember, Moshe said that oMFS introduce lots of problem.....i 
don't remember exactly what problem it is...maybe seg faults on certain 
conditions etc

In the other hand, merging oM with famous parallel/distributed FS like Lustre 
will benefit oM, because we do not need to maintain the FS, only the kernel 
itself...right Moshe?

From what I read, moving oM to user space means to move some part of oM as 
user space apps, but not all of oM

for example, the info daemon....this is targeted to be 100% user space daemon

Yes, but we need more effort to sync it with every new base kernel release. As 
you know from the current condition, on each kernel release (2.4.22, 2.4.24) 
the oM developers needs to adapt oM  according to current scheme, eg: VM 
change, process management etc....this can be painful if being done 
repeatedly...so if we can move some part toward user space...the pain will be 
lesser

About openGFS and Infiniband, I'll let others to answer

regards

Mulyadi
