TITLE: Example of Banach spaces with non-unique uniform structures
QUESTION [10 upvotes]: While it is known that compact Hausdorff spaces admit unique uniform structures, it is further shown by Johson and Lindenstrauss's result that Banach spaces are characterized by their uniform structures [Johson&Lindenstrauss&Schechtman]. [Ribe] pointed out that two non-isomorphic spaces may have homeomorphic uniform structures (See [Benyamini&Lindenstrauss, Chap 10, Sec 10.4]).
The classical nonunique example in [Benyamini&Lindenstrauss, Chap 10, Prop 10.32-10.34] shown that p-convexified Tsirelson spaces $\mathcal{T}^{(p)}$ for $1<p<\infty$ admit exactly two different uniform structures. 
Is there an example that a Banach space $X$ admits more than two uniform structures?

REPLY [10 votes]: In Theorem 5.8 of my paper with Lindenstrauss and Schechtman that you reference we show that for every $n=0,1,2,\dots$ there exists a Banach space that is uniformly homeomorphic to exactly  $2^n$ mutually non isomorphic spaces. AFAIK, it is still open whether $2^n$ can be replace by any number that is not a power of $2$. See (5) at the end of the paper.
