Is there some way I can set up a page with a contact list where the only mechanism to contact the people is via a private message?

Something like:
Group X meets mondays 7pm, Contact Fred Bloggs for more info <click here="here" for="for" private="private" message="message"></click>

PostContact might get you started. Click here. You might have to do some minor changes to it to make it work for your purposes.
