Separating embedded compiler from Eclipse IDE

Would you mind sharing the lawyers' arguments? You got me curious on this.

ScalaIDE (eclipse plugin) is under the same license as Scala itself.So if you can't use ScalaIDE, then you can't Scala (library and compiler) (except if you can use ScalaIDE because you can't use Eclipse)

The lawyers don't share their thinking with me (ha, ha), but I believe that they don't want to conduct multiple reviews of the same item, and they probably want to split the reviews for the IDE and for the compiler, since each license is free to change independently. ...something like that, anyway.
If there's no straightforward way of getting the IDE to use an external compiler, I'll try to get them to review the IDE/compiler bundle.
Does anyone know whether the IDE and compiler can be separate?  If not, I'll experiment myself, and respond to this email.

There are different degrees of separateness. The compiler/library that
comes with the IDE are packaged in their own plugins.

You cannot use the IDE without any compiler, because all semantic
actions (hyperlinking, completion, report errors as you type, etc.)
are handled by the compiler. Also, you cannot just point the IDE to
another compiler version, since there may be (and there are) large
changes in the compiler API for IDEs between different versions.

As David has mentioned, the IDE uses the same license as Scala, so
maybe that can help.

FYI* to contribute to the IDE, we sign the same CLA (Contributor Licence Agreement) as for Scala.  I signed the same paper.* the licence of the tools scalac, scalaIDE doesn't impact the edited source or generated bytecode.
Check with your lawyers, but I think you can use any IDE you like to build in dev phase (on your desktop), and build the artifacts (your company use, share, sell) with a command-line tool like make, ant, maven, SBT, home made script (any thing approved by lawyers)
