How common is Plesk control panel with hosts ?
 

Currently with Webintellects and using Plesk 8.6 for forum backups but occured to me that if armagedon took out not just my server but my host company entirely and I had to find another host ASAP the new host would probably have to be using Plesk as well. Reason being the Plesk backup/restore seems to utilize a unique file compression code so I might not be able to restore the database unless the new host also used Plesk.
