How can I approach to develop custom remote blob store provider (RBS) for SharePoint 2010 which can take advantage of Windows Azure Blob Storage?

Little background to put this in perspective-
We have recently finished migrating a SharePoint based solution (entire farm) to public cloud based on windows Azure Infrastructure as a service (IaaS).
We do have certain components (not based on SharePoint) which are running on web role (PaaS) VM and machine level communication is happening in between (they all are using same DNS and V-LAN under same affinity group).
We are using IaaS virtual machines as db server for content and configuration database for SharePoint.
But we are also using azure storage (Table) to log information from non-SharePoint component of the system (Web Role).
It’s now completed successfully but I am curious if we can use the Azure blob storage as RBS provider to store all the BLOB content (as the application entirely in cloud under same affinity group and V-LAN network latency would not be of much issue).

Whether it would help to gain performance of the content db better?
Whether it would be more scalable (as azure blob storage is certainly tailor made for it)?
Additionally I also want to know in case we have fail-over cluster or mirroring in place can RBS creates any problem?

Thanks in advance
