Sharing EBS snapshots on EC2

If you want to share an EBS volume snapshot on EC2 with another account the Amazon documentation explains how: find the account number of the target account, right-click the snapshot on the management console, choose permissions, and add the account number. What the instructions don't say is that you can't actually create a volume from that snapshot on the target account---it won't show up on the list. You have to use the command-line tool ec2-create-snapshot.
