Live CD Anyone?

You can always have an NTFS host OS, then slap Back|Track in when you are at the Con. This way the 2.6 kernel (which cant write to NTFS) could be compromised, but nothing permanant would be probable.

Of course read access is still possible, so dont store NTLM hashes in yer registry or have personal data on the laptop... Strike that, bring lots of pictures of your WIfe, and pictures of your Girlfriend for teh people to post ;-)
