great!

yes, its in the pipeline but no one on the core team is working on that 
right now (i'm sure someone will jump on me here if i'm wrong ... :) ).

I looked into this a while back - if i recall correctly from our 
currently supported cloud providers only EC2 and Gogrid offer 
'mountable' storage volumes (ie EBS as opposed to 'cloud storage' - like 
s3). I dump some notes here that you might find useful:

* the ec2 api @ 
http://docs.amazonwebservices.com/AWSEC2/latest/APIReference/ includes 
the calls for EBS volume management - including CreateVolume, 
DeleteVolume, DescribeVolumes, AttachVolume, DetachVolume, 
DescribeAvailabilityZones

* gogrid:
* http://wiki.gogrid.com/wiki/index.php/MyGSI
* nes pas possible - they do have "cloud storage" : 
http://wiki.gogrid.com/wiki/index.php/Cloud_Storage:Cloud_Storage
* but this is storage that you can access only from your gogrid servers 
- attachable/mountable storage for your instances, not generic 'access 
anywhere cloud storage'

awesome! please let me know if you need any info/pointers to get started 
on this (probably a good place to start is #deltacloud on irc freenode - 
we all hang out there),

all the best, marios
