I would say yes, it is worth it. A few extra seconds on the backup job 
to collect BMR data, a BMR server for each of your supported platforms, 
and you get a simple way to get all your data back along with the 
configuration. I too witnessed a moderately complex windows system come 
back to life after booting from a CD, answering a few questions, then 
walking away while the tapes wrote all the files to disk. I did a proof 
of concept test on a sun/solaris server, and when completely configured, 
you type 'boot net' and walk away. A solaris install can take a couple 
of hours to put down the OS, run the patches, and configure everything 
to support the application you are trying to recover, so a feature like 
BMR can save a lot of time. I never got to test out the PXE boot and BMR 
feature for linux.

The windows recovery methods that involve a clean install can take just 
as long if you have a series of applications that each take their own 
time and set of skills to install. With BMR, everything you need to get 
the system operational (assuming you can successfully recover from the 
last backup) will be put down on disk. BMR is likely to save a bunch of 
time if your dynamic data (a database for example) lived on a disk and 
drive letter that did not completely fail. You can add NIC drivers to 
the bootable CD to support a variety of network and system 
configurations. It's in the docs.

BMR would be handy as a backout method for systems about to be 
significantly upgraded.
