Feature requests sent via Telegram.

Key features that our team wants to see added to the grid:
-Snapshots
-scheduled backups
-Ability to start new VMs using backup or snapshot.
-Ability to add multiple users to same wallet privileged access
-Deployment filter that verifies if node has public scope global IPs
-Ability to keyword search contracts and deployed machines
-Ability to deploy a domain instance with additional ports outside http.

On the ports, if you can make ipv4 to ipv6 translation easy for UDP, TCP, etc. Haproxy is a great existing tool for this.
