Unknown Monopodial

[Acharn]

This was a gift in Thailand along with some Vandas and Dendrobiums. I was thinking it might be a Rhyncostilis, because that's the other popular monopodial in Thailand. The plant is about 3 inches tall -- it's sitting in a wooden slat basket that's 9 inches at the top, 4 inches at the bottom, and about 6 inches deep. I'd love to get it out of this large basket and into a smaller one (maybe 3 inch), but the roots are strongly attached to the wooden slats. The leaves are much flatter and thicker than any of the Vandas I have. Can anyone identify it on this basis, or will we have to wait for it to bloom?
