Not sure how it works in the US, especially because every country has its own rules, but I don't think there will be any problem. There seems to be no mention of any pay so it can be treated as any other University project (I guess). In my Master's programme (Studying in Amsterdam, so not an american) we can choose to work on University-approved projects(it's up to the professor) and can receive credits for them. A few friends of mine have worked at GSoC projects and got credits from those, I'm currently doing some independent research with a mentor/tutor and will get credits once I finish (and hopefully publish). This doesn't sound any different.
