We use many mount points and symbolic links inside the Cyrus partition. 
Should work the same way for virtual domains and a direct mount. The 
only draw back is that singleinstancestore won't be as efficient as hard 
links can not be made between mount points. But it is better than 
running out of disk space. :-)
