yes, we already have at least 4 or 5 implementations of WebAccessControl.

Even though WebAccessControl mostly described in terms of WebIDs it can easily
be extended. For example I have extended it to also allow WebKey authentication
so that it can work with https://tools.ietf.org/html/draft-cavage-http-signatures-05

The code to do that is quite short:
 https://github.com/read-write-web/rww-play/blob/dev/app/rww/ldp/auth/WACAuthZ.scala#L56

The test suite for WebKeys:
  https://github.com/read-write-web/rww-play/blob/dev/test/ldp/WebTestSuite.scala#L93

One could also enable OpenId authentication too, and other schemas.
