Well, I guess there wasn't much to discuss on this topic. Nevertheless, I have 
written a few articles about it which might be interesting to someone:

"Filesystem Familiarisation"
https://blogs.fsfe.org/pboddie/?p=2407

"Using ext2 Filesystems with L4Re"
https://blogs.fsfe.org/pboddie/?p=2420

"Filesystem Abstractions for L4Re"
https://blogs.fsfe.org/pboddie/?p=2431

"Integrating libext2fs with a Filesystem Framework"
https://blogs.fsfe.org/pboddie/?p=2457

"Dataspaces and Paging in L4Re"
https://blogs.fsfe.org/pboddie/?p=2469

The earlier articles are more general, with the latest one actually dealing 
with L4/L4Re specifics. Of course, my thinking about such matters is still 
rather fluid, and I will need to look more closely at Hurd-on-Mach, but 
perhaps it is interesting for some to see the mechanisms available in other 
microkernel systems.
