Jeremy,
Glad to hear that you have things working with Mijoshop.
A profile plugin to automatically import information is planned, but I don't have a real timeline on when it would be available. The v5.0 release makes the profile plugins much simpler to make, and the upcoming v5.1 release should make it even easier while also adding more social networking authentication support. Once that release is out, we're planning to create quite a few profile plugins for integration with 3rd party systems, and Mijoshop is definitely on that list.
So, we should have something by year end to let you import data from multiple social networks, in addition to LinkedIn and Facebook, into Mijoshop... but just not yet.
I hope that helps answer your question, even if the timeline isn't exactly what you were looking for.
Thanks,
Alex
