This is indeed a thorny issue. The developer of OcalIDE is taking
another stab at this but this time using Camlp4 [1].

BTW the way the Haskell eclipse plug-in [2] also has to deal with such
issues. In their case they use a generic library and API [3] that should
be usable by any number of IDEs and editors (already used by emacs). May
be of interest to you also.
