In this particular case we have to be very careful, because SLF4J is an
extremely popular and widely spread piece of software and we are talking
about API naming.

As SLF4S is not a (bridge to a) logging backend, I think it should have
"api" in its name just like slf4j-api => slf4j-scala-api or slf4j-api-scala.

I agree with you that we have to use org.slf4j as the name of the root
package.

If we are going for subpackages, then org.slf4j.scala would probably be the
best choice. In Scala versions prior to 2.8 you better didn't use "scala" as
a package name, but SLF4S is for 2.8 and higher where this isn't an issue
any more.

But nevertheless I don't like using "scala" as a package name. First it
simply feels wrong, but that's probably just me. Second and more important,
there is no semantic value in "scala". Therefore we could also choose a
different approach: Just use org.slf4j as the package name and call the
types differently. Actually it's only Logger which is used in both SLF4J and
SLF4S. Why not call it SLogger (for ScalaLogger or SmartLogger or ...). How
do you like that idea?

Regarding OSGi support we of course would have to make the slf4j-api-scala
module a fragment of slf4j-api in order to avoid the split package issue.
