[Rd] Anyone using Interwrite PRS clickers?

[Duncan Murdoch]

I've agreed to use the Interwrite PRS "clicker" (an RF input device that 
allows each student in a class to respond to questions) in a class next 
year.  The version of the PRS software we're using stores its files in 
an undocumented (AFAIK) but fairly obvious format, a mixture of XML and 
CSV files.  Is anyone else interested in working with this data from 
within R?   I'd like to use it to have R drive the process; I don't 
think that's possible, but R should at least be able to read the results.
