Object Storage and Cyrus IMAP

[Marco]

Hello,

    I see that Cyrus IMAP 3 can interface with some Object Storage such 
as Caringo or OpenIO.

Is anyone using these solutions?

I would like to know how I can find more details about these deployment, 
other than the brief description in imapd.conf man page.

In particular I would like to know if these interfaces are stable and 
supported in future releases of Cyrus IMAP.

Do you plan to add wider support to object storage, maybe by adopting 
some standard vendor independent?

I thank you very much for every info you could provide.

Warm Regards
