thnx Carlos for your ambition Carlos
I'm not much of a developer but for what it's worth here my thoughts:

Your #1) sounds great, but does that mean object store or will it still be whole files that are handled?
up to now I loved the feeling of having at least my files on the bricks if something went really wrong and
not ending up with a huge number of xMB sized snippets splattered around (well I know pros and cons 
and depending on scenario and size, but still though...)

Your #2) could be incorporated in #1) somehow? "minimum 3 bricks, 1 per node" with kind of quorum mechanism???

As #3) I would vote for reliable encryption to be able to use third party storage, 
just speed??? is affected by to many other things, bandwith, speed of underlaing storage, different speed of different bricks...
so speed I would vote down on rank #4) ;-)

This is specially important because it has a HUGE impact on Total Cost of Implementation (customer side), Total Cost of Ownership, and also matching what the competition has to offer. Among other things, it would allow gluster to implement a RAIDZ/RAID5 type of fault tolerance, much more efficient, and would, as far as I understand, allow you to use 3 nodes as a minimum stripe+replication. This means 25% less money in computer hardware, with increased data safety/resilience.>

> 3) Accelerator node project. Some storage solutions out there offer an "accelerator node", which is, in short, a, extra node with a lot of RAM, eventually fast disks (SSD), and that works like a proxy to the regular volumes. active chunks of files are moved there, logs (ZIL style) are recorded on fast media, among other things. There is NO active project for this, or trello entry, because it is something I started discussing with a few fellows just a couple of days ago. I thought of starting to play with RAM disks (tmpfs) as scratch disks, but, since we have an opportunity to do something more efficient, or at the very least start it, why not ?>
