I'm a paid up customer of yours, love the product, but it's a shame you won't have a Leopard version ready to go on release. Are you not part of ADC?
Out off all the Apps I use, SuperDuper and Tunnelblick were the only two that aren't ready yet - but the developer of Tunnelblick (an open source app) emailed an updated binary which works fine.
I guess I will have to use Time Machine for backups to start with, which is a shame, as I think doing a full system restore would be a pain. You can't even boot from the backup drive
I could go on about Time Machine, it could have been so much better, but this is not the place.
Looking forward to the next release of SD
