IMHO there are better ways of dealing with system management like not 
giving users root access in the first place.

Developers can have root on their dev boxes of course - but the idea of 
developing on the same box you use to access the 'net (generally your 
workstation) has always struck me as counter-productive.  You want your 
access to the net to be rock solid - exactly what a dev box isn't.  With 
near univeral access to the network and virtualisation technologies there 
is no need to tie development to the box you happen to be physically near. 
Where I work now I have setup a virtual dev environment (using OpenVZ) so 
developers can have a new dev box shortly after asking for it, and they 
can work from the office, home or elsewhere over the VPN.  No problem.

Like a lot of other commercial products DeepFreezeLinux strikes me as an 
MS-Windows focused tool which has been ported to Linux.  Some might find 
it useful but it isn't for me.

A lot of the time people use Linux on the desktop the way they use 
MS-Windows.  The Linux approach is alot more flexible than that (and to 
give it some credit, MS-Win has caught up a little bit in recent years).

I can ssh in to dozens of boxes transparently[1] from my thin client. 
Thus my computing environment becomes a network rather than a computer.

Future OSes are going to move even further in this direction but what we 
can do now is pretty good.  Even carrying a laptop within a city will be a 
thing of the past one day.  As time goes on the range in which this is 
feasible will continue to grow.

Yeah I went off on a tangent a bit but all too often I feel that the 
limitation on using computers is a lack of imagination.
