ERP software

I was just playing around with the R-streams package, reading in some data
from an old experiment we did here, and was again amazed by the flexibility
of the R environment. The eaze with wich I was able to generate simple plots
of my EEG data made me wonder if someone tried to implement an ERP package.

For the non-cognitive scientists ou there: EEG is electrical activity
measured from the scalp (usually multi-lead) that is used in
psychophysiological experiments to infer cortical activation. In a typical
experiment this data can be linked to events: usually stimulus
presentations, to calculate 'trial means' in distict trial subcategories.

Did someone out there made an effort to put together some sort of package
for the analysis of this type of data?
