Advanced Topics in Computer Science
A survey of interesting "latest and greatest" issues that are being explored but haven't quite hit the main stream yet, or are just starting to get attention, or that are not being leveraged fully yet. For example GPU computing, multicore computing, or scientific computing clusters might be a topic.
This might not be a good area to work on for side-topics or break out sessions, but I could see at least one main topic being presented as part of the regular main sessions. Additionally, if you have a limited number of locations for travel, you might also be able to get someone from a local university to come in and give a presentation on a topic.
