It is... I've added a simple meshing command in the script language:
with tomorrow's nightly build you should be able to use "Mesh 1;", "Mesh
2;" and "Mesh 3;" to mesh in 1-D, 2-D and 3-D.
But then again, if you just want to generate meshes from an exterior
program without interacting with Gmsh, the simplest way is to just run
Gmsh using a system call (e.g. system("gmsh mymodel.step -3") on
Unix)... Then read the mesh from disk and you're done. Using sockets
will not give you anything more.

cf. utils/misc/driver.cpp. Beware that the API is not frozen, so it
still changes quite frequently.
