Hi Akshit, glad that you want to get involved! I'm looping in meejah since you said the magic words 'txtorcon', and he would be the primary mentor for that. ;)
To get acquainted with Tor and Stem, I'm working on a patch[2] for stem with Damian's help. I'm going though txtorcon's code as well.
Thanks for the help with that! As mentioned on irc I'll be giving the ticket another pass when able. As for the txtorcon/stem integration project, I just updated the volunteer page entry for it to clarify the project a bit...

That project would be a grab-bag consisting of several small, bite sized tasks. Unfortunately we don't quite know where the project should go after what we listed there so you might want to brainstorm additional directions that it could go.
Cheers! -Damian
