Lonneke Dikmans already blogged about the possibility to submit and nominate sessions for Oracle OpenWorld 2008. This is one of the ways to get involved in the Oracle community through Oracle Mix.
I submitted an idea called "Putting SOA to Use". This session is based on experiences from a customer-case in which a Service-Oriented Architecture is implemented using Oracle technology such as BPEL, ESB and WebCenter. Read it and if you think it’s interesting vote for it!
