Thanks, searching for "Tom" and reading his comments those questions still seem relevant although
do you know if "markdown" or whatever the web math thingy is somehow related to this session?

I played with a server version of "R" and a custom made java server and always wondered if there
is any use for a server version of tex. That might sound dumb as both can be quite slow but the server
I mentioned made heavy use of caching ( it was for custom ads generated in response to
a specific web page irequest and whatever is known about the viewer ). 
Similarly with math or even dynamic web content a lot of it is reused anyway and better
caching could make even slow things practical. In my  case however if you want to send a tex like
source code to a browser and have it generate dvi or pdf locally client side then caching would not help.
Although apparently from the commentary here a lot of markdown just generates requests for 
rendering by a third party and that is quite slow  ( beyond roundtrip web latency )
but not sure why if caching is cheap.

In any case incremental dvi does seem to have been explored before.
