The Sun Java pricing model just seems nuts to me (quote from a CNET article):

Sun is also launching per-citizen pricing for its Java Enterprise System server software. While the company had committed to the idea earlier, it now has begun selling it according to population and how the United Nations ranks countries as more, less or least developed. Countries with larger populations and lower development pay less per citizen.

"Governments--when delivering driver's licenses, health care or fishing permits--tend to serve massive marketplaces," Schwartz said.

Under Sun's pricing, Mexico, a less-developed country with a population of 100 million, would get to use as much Java Enterprise System software as it wants for a charge of 81 cents per citizen per year. Nations classified as "least developed" pay between 33 cents and 75 cents per citizen, while "less developed" nations pay between 33 cents and $1.95 per citizen, spokesman Russ Castronovo said.

And how, by the way, does this make Java Open Source? Perl is Open Source, lemme see, the pricing model is, oh yeah, $0 no matter where you are. Same thing for Python, Ruby, TCL, GCC, Linux, etc. So what is this Open Source Java business about?
