I think you can go for it and send it. Ideally the samples should be sent cold but I send other organisms through the mail all the time without putting them under ice. In fact freezing them and then sending them will drastically reduce viability as they thaw. In the summer it is a bit hot but you could send a liquid yeast culture in a screw top vial to get a lot of yeast growing in there in case any die.
I am starting up a Home Brewer's Yeast Collection that will deal directly with mailing yeast cultures through the mail.
