I had an idea this morning and would like to share and to know if someone has already developed it somewhere!
Using that and an online text editor (codeMirror), some application of mine are running PDFlatex on server side...providing some (La)TeX online facilities. This is common.
This would provide access to (LaTeX) source code of any scientific paper... rather to reinvent a Math formula and if I'm not wrong, This it IS the idea Knuth had few decades ago when building TeX. People should share (La)TeX code, not DVI, PS nor PDF code. The client browser (Firefox, Chrome, Opera, Safari and others) should handle PDFlatex process locally!
Let me explain my requirements another way;
I am working for the industry for 20 years and I use to use TeX and LaTeX at University like many of you I guess. Looking at our real main requirements in documentation systems, I think that Industry, at least critical embedded systems I work for needs:
A programmable document system; where you can can process customer requirements within informal English statements to derive and automate many things like requirement traceability, design doc, tests sequences,...
A very nice/professional rendering, perfect graphs, tables, diagrams...
Insurance that such document is such version and the content won't change. The Web does not provide some "digital signature/ digest" visible on print-out. The best "permalink","perma-content" system is the PDF format and that is why official documents are PDF (unfortunately, this is a not optimized format, but is it used every where you need static documents)
It is well known that PDF document produced from LaTeX satisfy really better those requirements than MS Word or other LibreOffice when only the latter are used in the industry.
What may change this approach is the arrival of "cloud computing", not a revolution idea by itself, but the fact that you are never Downloading files.
The jsPDF extension from Mozilla and the Chrome embedded PDF reader are making the first step, showing that PDF are really like other HTML pages (Google is also finding them) and this is very important for industry that requires those static (permalink/perma-content) documents.
Because best quality PDF are coming from LaTeX/TikZ source, it is now an opportunity to provide to the industry a real efficient document system on the cloud.
But if you (TeX experts) are fighting on such or such tiny advanced function for a variant of TeX, we won't have any chance to see a Web LaTeX and more important any chance to see LateX used in the industry one day.
