Maemo and Moblin both use mozilla based browsers. Maemo comes with MicroB and Moblin comes with the Moblin Browser. Both can also use Fennec or Firefox Mobile. There may be some WebKit projects floating around for both of them, but I don't believe any of them are far enough to replace the platform browser. My guess is that the merger into Meego will continue to use Mozilla/Firefox.
Oracle already has a number of guides to building a cheap Oracle RAC setup. One of the more interesting ones used a firewire device that could support multiple logins. Thus creating a cheap and fast shared storage device to use for ASM and OCFS. The article is here: http://www.oracle.com/technology/pub/articles/hunter_rac10gr2.html. The setup here was only a 2 node system. I'm not sure if these cheap firewire drives can handle 3 logins. There is another guide for doing iSCSI, although I would think the firewire setup would be cheaper and faster.
