A recent article in Statistics in Medicine dealt with this issue by extending shared frailty models to the competing risks situation:
Katsahian and Boudreau. Estimating and testing for center effects in competing risks. Stat Med (2011). doi: 10.1002/sim.4132
It's pretty hot off the press and would require a lot of work to implement. I am not sure if you can use a model based on Cox regression, eg Lunn & McNeil's method, in clustered data - but if you can it would almost certainly be a lot easier than implementing the above.
