Andy is right - everyone who is a member and has an opinion should right now be ringing their reps and getting it across.
If Ian has retained legal representation, then it is only natural to go for costs and damages. The likelihood of it ending up in court may not be that high due to the prohibitive costs on both sides, but one thing is for sure. This will be paid for by members funds in one way or another, and if members would like to see a speedy and less costly resolution, then it would be best if they started saying so formally.
As I've said before, good luck Ian. I've been in a protracted legal battle regarding trademarks before, and it isn't a nice place to be.
Edit: Ian answered regarding representation....
