Custom plugins get called via PVE::Storage just like any other plugin - 
the API 'contract' is a bit underspecified, but when in doubt just ask. 

There are a few places in the guest code where lists of storage 
types/plugins are hard-coded atm (e.g. 'list of storage types supporting 
vzdump backups'), but if one of those lists needs to be extended / 
switched to be generated via the API mechanism (e.g., by each plugin 
stating 'I can serve as a target for vzdump'), I don't see a reason why 
not to do it.
