In a new preprint (http://arxiv.org/abs/1105.3658), "Spacetime Geometry as Statistic Ensemble of Strings", Botta Cantcheff argues that space is an ensemble of "strings". He explains that the thermodynamics of strings reproduces the derivation of the field equations of general relativity by Jacobson. By strings he means some one-dimensional objects that are similar, but not exactly the same as the strings of string theory.
So here is a further researcher that understood that space is a collection of one-dimensional lines. He agrees with what Carlip says, and with what Schiller says, who argues the same connection between general relativity and the thermodynamics of strands. And he arrives at the result independently of them. A good sign!
