Some background would be nice. Wasn't LaTeX notoriously hard to port – to the point that a LateX app for iPad actually ran in an emulator initially [1]. Is this port based on web2c as well?
I'd also appreciate info on whether Latex packages will be supported in the future. At the moment this does not seem to be the case, though I can imagine this would be a challenging problem to solve for in-browser compilation of documents.
In theory one could search the LaTeX code for '\usepackage' stings and download the required files and mount them into the virtual filesystem of emscripten.
