My dojo is in the back of my mini-van. I can throw those mats out in the community center or the park. If students come fine, if not, I train with my son's. But to me, the most important thing is that I am training. Now, if I were still in Okinawa, I would be training at Okinawa Aikikai and have no reason to open my own dojo. As it stands though, I really don't mind a "traveling dojo."
Hey, there's something to be said for your traveling dojo.... Your landlord won't be hiking your rent or evicting you to build luxury condos.
