The further mainstreaming of geekdom: who needs Tupperware parties when you can have a keysigning party? This HOWTO has the compleat formula for throwing an event that's both educational and privacy-enhancing!
3.3 What Participants Should Not Bring to the Party
1. A Computer
3.4 Why you should not bring a computer to the party
You should not bring a computer to the party because binary replacement or system modifications are very easy ways to compromise PGP systems.
If someone where to bring a portable computer and everyone used that computer to sign the other keys at the party, no one would know if the machine had been running a key stroke logging utility, a modified version of GPG,a modified version of the Linux kernel, or a specially modified keyboard, any of which could be used to capture the secret keys of those who used the computer.
The use of a computer at the party would also leave you open to more simple attacks like shoulder-surfing, or more complex attacks like weak secret key generation, secret key modification, or even infection with virii that modify your GPG binaries to leak future secret keys discretely.
