Because we've already have had a couple of questions about this, in their current forms, StableBit DrivePool works VERY well with StableBit Cloud Drive already.
The StableBit CloudDrive drive disks appear as normal, physical disks. This means that you can add them to a Pool without any issues or workarounds.
Why is this important and how does it affect your pool?
You can use the File Placement Rules to control what files end up on which drive. This means that you can place specific files on a specific CloudDrive.
You can use the "Disk Usage Limiter" to only allow duplicated data to be placed on specific drives, which means you can place only duplicated files on a specific CloudDrive disk.
These are some very useful tricks to integrate the products, already.
And if anyone else finds some neat tips or tricks, we'll add them here as well.
