This has come up a few times in reference to the InstallFest so...

Yes, there will be access to the internet at the InstallFest.  Wired access is
definately going to be provided.  Bring a network cable if you want.  I don't
know if wireless connection will be available.

I don't know the status of dial-up connection capabilities.

I am told there will be no problems with power but you may want to bring a
power strip along to make sure we don't run out of them.
