If the changes make things better for people who have machines that are <5 
years old then making them slightly worse for people with ancient hardware is 
not a big deal IMHO.

Regarding building complex applications, there are lots of decently powerful 
machines on the net that you can use for such things.  I've got a machine 
with 2*P3-1GHz CPUs, 2*18G 10,000rpm U160 SCSI disks (and a couple more disks 
available without cables), and a gig of RAM (might be able to find a second 
gig) that I want to donate for such use.  All I need is a place to host it in 
Melbourne (or someone who wants to pay postage to somewhere else that it can 
be hosted).  It needs an ATX 2.0 PSU, but I'm sure I'll find someone willing 
to donate that.  Incidentally it's the most powerful machine I've ever owned 
and it's significantly faster in every way than the machines I use for my 
regular work.  If it wasn't unreasonably noisy I'd run it at home.

The machine is aimed to be used as part of the nipl.net project (see 
http://www.nipl.net for details).  There is an admin team ready to run it and 
they want to use Debian.

If you are concerned about what happens when a machine crashes then you should 
want to have the commonly written transient files on a tmpfs.  Having a quiet 
file system is the best way of surviving a sudden power failure.  Note that 
there are many hardware issues related to power failure that ext3 can't fix.  
Data journalling can help but not many people use that feature.
