Great stuff! I'd love to use this in magic-wormhole.. I only need the DataChannel, though. Any idea how hard it'd be to define a 'feature' for the codecs, so pip install aiortc[video] gets you the dependencies on the codecs, but pip install aiortc[datachannel] does not?

Example of usage:

users = await User.filter(first_name__ilike="c%r")

users = await User.filter(first_name__ilike="j_r%")
