Bink.nu has some interesting information on Windows Server 2003 Compute Cluster Edition. It is 64bit only, and consists of 2 CD's. They also posted a set of screenshots.

"And again, you can run the same software on any Windows... why pay 5x more just to get an empty shell with a cool name? "
The cluster version is not yet a released product. It'll apparently include management software not available on XP - and a 2003 product need not cost as much as Enterprise Server. The "web server" version costs much less.
Regardless:
(1) How do you know how much it'll cost? Indications are that it'll cost LESS than Windows Server SE.
(2) How do you know what the license says?
You don't. You merely assume - and that poorly.
"You cannot just migrate any application to clustering use, you need to re-write it from scratch in-order for it to work in such an environment. "
Already done. Unless you somehow think someone buys a cluster to run Word.....
"Now, things get much worse, if the OS's kernel was never designed to be clustered: Instead of the kernel cloning a running process an migrating it to a remote node, the software itself needs to freeze it's current execute state and manually migrate itself to a remote copy of itself, running on the target node. "
None of this is correct. Not one word beyond "and" and "the".
Individual process will be started on compute nodes by the head node and communicate with MPI or PVM - as I've already said. There will be no "migration" of anything. There's no single system image. No single kernel running on the entire cluster. That's not how a Beowulf or NOW works.
