I'm not sure why we'd want to write our own SAC parser. Its a lot of work and there are clearly existing technologies which, while maybe not perfect fits, are better than starting from scratch.
I'd much rather work with an existing community supporting Flute or Batik (assuming such communities exist, the Flute files are all 2002 so not clear if its dead code or not). Just as with Eclipse, you see if the community is open to making the changes you need. If they are, you help make those changes. This gets you the technology you need, and meanwhile furthers that community. Everyone wins! And its a very efficient use of developer resources which are always scarse. I'd rather spend those cycles doing something more specific to Eclipse (like nice style sheets, like a UI model, etc.).
