I would like to point out certain locations specifically by line numbers or by some marking, how can I do it in long answers such as here? It would help communication enormously.
Chalks, where are they?

A magical real-time multi-user gestural touchscreen whiteboard interface would be pretty awesome, but let's face it, we're talking about StackExchange here, and not, say, Industrial Light & Magic. You might as well ask for a pony while you're at it.
Equation numbers can be added by including \tag{n}
at the end of the equation, as JavaMan said in a comment. If you need to refer to equations in someone else's answer that don't have numbers, you can do two things:
Earn 2000 reputation points as fast as possible. Then edit their answer to include equation numbers, and refer to the numbers.
Post a comment saying, "Your post has a lot of equations and I need to refer to a specific one. Can you add numbers using the \tag{n}
command?" Hopefully, the author or someone else with 2000 rep will come along soon enough and edit those in.
"A magical real-time multi-user gestural touchscreen whiteboard interface"
would be awesome -- that is a challange for OCR and FPGA developers among quants/etc --What a PONY challenge, let's do it :P

I know one way of doing this: building iPad -site or iPad -app for Math SE but currently not feasible because of the restricted API. This so-called site could act like a virtual chalkboard -- it could be super-cool.
Initially, I probably thought this problem the wrong/hard way i.e. through OCR such as here, here and here -- but in reality, you can get this problem into much simpler form if you develop the site on something with touchscreen, otherwise I cannot see how to do it easily. With specified framework, it should be easier -- I may be of course mistaken.
There may be other solutions.
