1> Novell is using linux in one of their best products (oddly, the one being referred to here - ZENworks is an _AWESOME_ product for managing software distribution. No free software equivalent floating around that I know of - anyone want to point me at something that handles association of users, workstations, and applications in a central directory, remote control/view through the directory, single sign on through the directory, self-heal capable applications, desktop imaging and update snapshotting, and works on Win32 boxes that universities and businesses love so much? It's better in a lab or office environment than on people's 'customizable' machines, but it is a __GREAT__ product.
Personally, I'd rather run linux - but there's too much vertical market software that will _NOT_ run on it. And then there's my cd burner that Adaptec likes and cdrecord doesn't... Or even shrinkwrap with no good replacement - ACT! and Visio were still better than equivalent open source / software freedom movement packages last time I looked at them (three months ago). Depressing, since I've been using linux since i had someone with a 'real' connection make me up 1.2MB floppies of SLS....
A slightly pricey ($2100 or so) solution: the Tiqit matchbox PC - a 486 in 5 cubic inches. I saw these at PCExpo last year, and it _really_ looks like a solid solution for putting a remote instrument out there. Since it has an internal disk, you can even keep the data streams local and handle your sensors over the serial ports. It'll run a light kernel quite happily, too.
the other $600 is for a 1.2M or 2M wireless ether node (used or clearanced as the Lucent 11M parts obsolete the 2M), and a wireless card for the management PC. It's pricey, but you end up with a self-contained PC that should be able to handle a ridiculous number of sensors. If you need realtime, it gives you the option of using 1M, 2M or 11M ether (11M ether is still _quite_ expensive for the 'hubs'), or locally storing the data on the acquisition device if realtime isn't an issue.
This functionality has been available on higher-end RAID controllers for years (read Compaq Intel servers). You can have a power supply cook off, kill the system board, and if it doesn't take out the array controller, pull the dead system board and power supply, replace them, and (theoretically) have it finish the disk writes once the system powers back up. I believe this was the SmartArray product - it's been 6 years or so since someone tried to sell me one for a 50 seat novell network.
NFS is not a 'good' tool for network file sharing - just the accepted one on Unices. From a performance perspective, it's just not there.
Further, the point of the question isn't file-and-print-services, it's file-and-print-and-DCOM-and-remote-Database-and-*s earches for good client/server hotbutton* directory-enabled pushed-to-desk-application deployment (i.e. Novell's ZENworks for Desktops, but with support for multiple OS/architectures and a (sigh) better UI)
From an historic perspective, without Greek civilization surviving the Persian invasion (i.e. they became another servitor nation to the Persian empire), western society would look a lot different.
Besides, who said western society was good?
Frank Miller also did a very very nice piece of work last year, short-run comic series "300" about... you guessed it, the Spartans at Thermopylae. Doesn't have the depth that a careful historic treatment does, but it is a fine example of what can be done in the comic medium for a story of true heroism.
