but i would like to know if anyone is working on this or even considering working on this.
Since no one has said anything, I don't think its being worked on.
Besides that, it's quite a lot of work:
- you need a driver for the actual network hardware
- you need a network stack
- you need at least a basic browser
given that none of that is a trivial task I bet this will never happen. Also, as only a small number of targets do have a micro SD slot and therefore could use something like that the possibility decreases even further, and I'd say it heavily decreases. Rockbox is still meant as an audio player ...
