Personal link/bookmark manager for internal use?

I’m searching personal link/bookmark manager for internal use with poor results. Does anyone have experience about these?

My requirements are:
- PHP + MySQL
- Internationalization support
- Categories and/or tags support
- Import/export to web browser would be nice too but not required

Web services like del.icio.us are not an option in this case.

Make your choice here :

As i see sabrous is the best rated one in this list.

But as your i using MODx you can probably use customs Template Variables to do this.

Many thanks!

Sabros.us seems to be open source and stable too. Will definitely try this one.

I thought about doing this with MODx but I have a too tight schedule right now and this is more like a separate project. Maybe with modified Ditto snippet this could be accomplished quite easily?
