Launch/Coming Soon Page Plugin

Is there anything on here, or elsewhere, that is similar to the Coming Soon Pro plugin by SeedProd, or Coming Soon Pages by NetChillies? (I would provide links, but I'm not sure if that would be permitted...)

The first one is incompatible with Buddypress, and the second one does not allow for network activation.

I am really just looking for a simple launch page solution for my Buddypress multisite project, and I'm open to any clever workarounds that anyone might suggest.

Any help would be greatly appreciated. Thanks!
