OK, I answered my own question, but the answer may be useful to others. I downloaded the Linux version of the LimeWire installer and ran it. Much to my surprise and delight, it installed just fine under Solaris 8 on my Sun Ultra-1E. The only installation error was in the "create link" item near the end of the install. I'm not sure what this is supposed to do, but I just created my own link as a shell script (cd /usr/local/Limewire;sh ./runLime.sh) and it works fine.
