So I guess for 32GB, it's:

- Sealing: Done once. 3-4h compute on one CPU initially, plus 2-3 hours on a few CPUs.

- Proof of space time: 10 minutes of GPU time per day.

What are the latency expectations within the system when my node is asked for a Proof of SpaceTime? Is it feasible to keep the sealing data, delete the file itself, then spend ~5 minutes downloading the 32GB on my 1 gigabit/sec home Internet connection when someone asks me to do the Proof of SpaceTime, and return the Proof of SpaceTime in 15 minutes (5 min to download, 10 min to compute)?

Thanks again for engaging with me here! It seems the compute time itself isn't a constant enormous cost necessarily.
