A bit late getting a report in...
I attended Camp Trans this year, and I attended The Michigan Womyn's Music Festival, too. I learned something from both.
While I expected Camp Trans to be predominately trans-women, there were plenty of trans-men and many self-identified gender-queers. At our nightly community meeting everybody identified themselves by name and preferred pronouns.
The MWMF opens its gates on Monday at noon. People queue up at the closed gates as early as 4 AM. This gives an opportunity for the Camp Trans attendees to walk along the line, chat with people and try to build support for trans-inclusion. I was in one group of four people "walking the line". I had been afraid that the tone of this action would be too protest-y or confrontational, but it remained very friendly. Most of the people we spoke to were very much in favor of the inclusion of trans-women. We ran into two cases of people who were adamantly against it. There was no possibility of dialog with them.
During the week there were many MWMF attendees who dropped by Camp Trans. Their support was amazing. One night at the Camp Trans community meeting it was announced that an anonymous MWMF attendee had donated money for a "scholarship" to send trans-women to the music festival. Volunteers were asked for, I jumped. To get the most for our money, we decided to send three trans-women on the last day of the music festival, Sunday. I know of at least four trans-women who had already gone on their own to the music festival this year without the slightest incident.
On Sunday morning, I went with another trans-woman up to the music festival gates. The gate personnel, who had seen us coming on foot down the road from Camp Trans, gave us a friendly shout, "Hey, we've been waiting for you folks all week long!". We said that we had to buy tickets and were directed to the ticket booth. We told the booth workers that we wanted to buy tickets. I added as an off-hand non-sequitor that I was a transsexual woman. They took our money, fastened on the armbands and wished us a good time at the festival.
I did have a good time at the festival. Everyone was nice and the atmosphere was great. One woman who I had met when she was guarding the gate came across me, greeted me by name, gave me a hug and said that she was so glad that I had made it in. As we parted I had to wipe the corners of my eyes.
So the long and short of it is, the trans-exclusionary policy of the MWMF is de facto dead. There are still grounds for objection, though. The music festival administration needs to explicitly repudiate the policy. An apology would be nice, too.
