It's possible, but FWDs are not really a viable solution for "pluggable storage". It also limits what the planner/optimizer can do, and (obviously) it introduces latency because there's network communications. FWD are a great thing when you need to occasionally access remote systems, but it's not a drop-in replacement for storage. For example, how exactly would you do consistent backups?
