As was recently pointed out by Cadoni, a certain class of two-dimensionalgravitational theories will exhibit (black hole) thermodynamic behavior that isreminiscent of a free field theory. In the current letter, a directcorrespondence is established between these two-dimensional models and thestrongly curved regime of (arbitrary-dimensional) anti-de Sitter gravity. Onthis basis, we go on to speculatively argue that two-dimensional gravity mayultimatley be utilized for identifying and perhaps even understandingholographic dualities.Comment: 8 pages, Revtex; (v2) references and footnote added; (v3) discussion  on page 5 revise
