I think it would be great if this could be integrated with kdevelop. kdevelop is quite modular, so maybe it's not impossible to do. kdevelop already rules as it is now, with this added it will become even better.
Eclipse is not bad, also for C/C++ projects, but it's huge and slow.
(same goes for OOo). Although KDE apps aren't exactly known for being fast and leightweight, compared to Eclipse (and OOo) they really are.
