I fully understand that Java is a general programming language and can do I/O. However, "Safe" Java subsets, like the ones used for writing applets or presumably the ones that would be needed for markets in CPU cycles, do not do i/o. One could add i/o to the suite, but that would be dangerous.

If I were as worried about Java security as Perry is, I would still consider running Java (or C or C++) programs as part of certain markets in CPU cycles because I would trust their source. (IMHO, much better than trusting every web page I access.) A single example. I could see a network-wide factoring attack on the key NSA uses to GAK the extra bits in Lotus Notes. Such an effort would run a single program, which would be available in source. Depending on the details, I could either compile the program locally, or down load a signed copy of the object code/class file. The same argument applies to rendering e.g. Toy Story. This restriction does not provide for CPU cycle markets in arbitrary programs, but I think that a significant market could still develop under this limit. ------------------------------------------------------------------------ Bill Frantz | The CDA means | Periwinkle -- Computer Consulting (408)356-8506 | lost jobs and | 16345 Englewood Ave. frantz@netcom.com | dead teenagers | Los Gatos, CA 95032, USA
