Hello,
I personal would like the idea of putting up a process that apportion part of the funds to existing trust funds (like the IETF endowment) or any other program. However anything that would imply spending significant part of the funds on administrative matters like setting up a separate department or ICANN putting up her own trust fund can/should be avoided as much as possible.
The suggestion of hearing experiences of those who manage donor funds at ICANN58 is a good one, it can also be during one of the calls.
Cheers!
