comment In what sense is Taniyama-Shimura the $n=2$ case of Langlands?
So is Taniyama Shimura only Langland for n=2 for the representations coming from elliptic curves?

But do all degree 2 representations (are we restricting ourselves to irreducibles?) appear as actions on the first cohomology (by whatever definition) of some elliptic curve?

comment What are the sections of $\mathbb{C}\rightarrow \mathbb{C}[[x,y]]^{alg}[\frac{1}{xy}]$?
I actually think you're right, now. There are no sections... There would be sections for things like $\mathbb{Z}[[x,y]]^{alg}[1/xy] \otimes \mathbb{C}$ which I confused with $\mathbb{C}[[x,y]]^{alg}[1/xy]$.

Qiauchu, I wonder what you realized that made you remove your last comment. I am now quite confused myself by this...

comment What are the sections of $\mathbb{C}\rightarrow \mathbb{C}[[x,y]]^{alg}[\frac{1}{xy}]$?
What makes this question interesting is that $\mathbb{C}[[x,y]]^{alg}$ (as well as without $alg$) is a $2$-dimensional ring, and when you invert $xy$ it becomes $1$-dimensional (because there is only one maximal ideal, which we remove). So there may be many maximal ideals in $\mathbb{C}[[x,y]]^{alg}[1/xy]$ but I don't know how to tell what they are, and whether or not they induce a geometric point (a section $\mathbb{C}[[x,y]]^{alg}[1/xy]\rightarrow \mathbb{C}$).
