Hi Roshan!

If you took on this project, it would have to be in Perl, since it would be part of our regular site (which is entirely written in Perl). It's okay, though, we can teach you. :)

We have an importing tool and a crossposting tool right now, but they only work with other LiveJournal/Dreamwidth-based sites. Basically, the crossposter becomes a client for other blog sites. The crossposting tool that we've developed mostly lives in the cgi-bin/DW/External. Import is a little harder, because we have to worry about whether or not the data is verified. Also, the code lives in a lot of different places. You can see the content importer code here: cgi-bin/DW/Worker/ContentImporter

(Don't worry -- your mentor will help coach you through learning how the systems work if your project is accepted!)

cesy already commented with the tickets for importing/crossposting to other services. I think that, for a single summer's project, it would be best to pick either importing or crossposting (not both) -- that will save you from having to learn both the importing and crossposting systems. :) I think crossposting would be easier for you to work with.

I think that crossposting to Blogger, Wordpress, and maybe TypePad systems would be a great summer project!
