I am one giving my full mental support to this one. Current status with only 
some snapshots available for testing is not good for me. I have a box in 
production using vimages and this will give me much easier method of testing 
things than it is now.

I am running an older snapshot for couple of months now with no problem and 
only one small issue - some spurious messages in syslog, which does not 
bother me enough yet to hunt the real reason for it. I did run a similar 
system based on older 4-X releases patches with great success too, so I am 
just waiting for this move in order to be able to test better and more what 
new we can do in this area.

I think so too. This is good time for this move, so the whole picture will be 
clear before 8.0 (and I would like it to be long before 8.0) so the dust will 
be long ago settled in that timeframe. I will surely try my best with this 
when available. In my eyes, necessary amount of conservativism in this area 
is already taken and we should take a move.

For me, even 6-9 weeks is somewhat too long, but acceptable. The goal should 
be to gain stable state in -current ASAP in the true sense of this 
abbreviation. And this needs some work, but the gain is tremendous in my 
eyes.

That being said, I can help only with testing and maybe some feature refining 
if some needs will be, but as I have current usage for this framework and 
some more in future (maybe, now just as an ideas), I am really interested in 
this move to happen.
