HashBackup: local & offsite Unix backup

I'm looking for tire kickers and feedback for HashBackup, a Unix backup program. HB makes compressed and encrypted backups that can be sent over rscyn, ssh, ftp, or imap to one or more remote storage areas you own, or it can send backups to your Amazon S3 account. It has block dedup, does incremental backups (always), the backup can be FUSE mounted, and it works well on VM images.

I need a web designer too, so referrals are welcome (prirun at gmail.com). Thanks!
