Gene and Paul: I think the remedy here is to create a post-installation 
script that checks for the proper setting. My experience with 
distributing customized versions of open-source software is that 
maintenance become a big headache as new versions of software components 
get downloaded and installed asynchronously by users.  (Given the 
frequency of security-related fixes, this happens a lot even on 'stable' 
systems.) To use this specific case as an example, I'd rather be able to 
overwrite an existing version of openssh with a new version---including 
possibly new configuration files that accomodate new variables---and 
then change the appropriate variables using the script, than have to 
remember to save off a customized configuration file, install the new 
version openssh, and then roll back the old configuration file with my 
fingers crossed that it still works with the new version of openssh.

Cool idea. The IEEE 1394 (aka firewire) standard says 4.5m between nodes 
is the maximum. I've heard of active extension cables that work with 
powered hubs but I've never seen one. The descriptions make it sound 
like you still have to string together 15-foot units. You'd probably be 
better off streaming video through ethernet---10baseT has a 100m 
limit---or using an IEEE 1294-to-fiber transceiver arrangement, which 
can work over very long distances but starts sounding like real money 
($600/pair of transceivers plus the price of the optical fiber). Still, 
a cool idea.
