ELL Aid from Verbling?

@Larryferlazzo introduced me to this new site as it was reported on by techcrunch.com. Verbling just launched on Friday. It's not a new idea: it appears that there are a lot of similar sites that are capable of doing this, but the structure of it sounds promising. The program pairs up people with native speakers of the language that they want to learn. So for example, someone who is a native speaker of say, Turkish, and wants to learn English, would be paired up with a native speaker of English, who wants to speak Turkish.  The conversation between both parties is timed, so that half is done in one language, and half in the other, and the site encourages you to switch partners several times throughout your session so that you are exposed to a number of different speaking styles and conversational topics. In addition each person is grouped by approximate ability, and topics are given to help facilitate conversation.

When I saw this come up in my feed, I immediately started wondering whether it could be used to help ELL students. Say I paired up the students with each other, based on interests in learning different languages, and then they had to teach it to each other. The site itself might be problematic to use in a classroom, (since I'm not sure how well regulated it is) but it might be interesting to  use the process with students, where native english speakers are helping their classmates learn english, and their classmates are helping native english speakers learn another language. This would not only help the ELL student, but would be beneficial to the other student as well, since so many people in the US cant speak any other language, and skills in another language can help immensely with mapping and comprehension. Conversely, if I had a student who spoke a language I wasnt familiar with, this would possibly be a good tool to introduce me to the language.
