Just started checking it out since I just had a couple of servers come 
available to play with. I like browser based VNC :-)  Not sure if its 
for me, I tried that network cluster storage before and never seen speed 
near local SSD storage. Other features for other user management, etc, 
all good. I'm really trying to see if it can help me setup Virtual 
Networks with two different subnets from the data center. Never did 
VLANs and want to try and isolate or clean things up in the switches. I 
basically use one subnet for the co-locations and the other for all my 
own stuff.

Sounds good, I'll have to give this a try now that I have some resources 
to do so... in my spare time :-/

Love BO! Been on it since the Cobalt days. Thanks Michael!
