I think you can use the -d option for tar, to create a list of differences since
the last full backup, for the daily backups.
I'm currently using the same backup scheme you are on a home network, except I do
incremental daily backups over NFS and full backups each Friday to DDS-2, keeping
the last Friday backup of every month. Works out to be 22 or 23 tapes per machine
per year. Less if each tape set backs up multiple machines. I only worry about
stuff on the lappy and webserver :)
