The limiting factor for Alpha is to find someone who can write the native method invocations in Alpha assembler. This should be a day or two work for someone who's proficient in Alpha assembler. I did some of the groundwork (basic stuff) and wrote a little about it on my web site (http://www.kjkoster.org/java/).

It is possible to run Compaq's Java 2 implementation on FreeBSD/axp. If you search the freebsd-alpha mailing list archives you will find crude howto's.

I'd be interested to read that article. Could you dig up an URL?
