Writing to two different dataspaces at the same time

Hello Genode Community,

i am new to Genode and i have two questions.

1) Is it somehow possible to back a virtual address range with two different dataspaces (attaching two different dataspaces at the same virtual address is obviously not possible) ? What i want to achieve is that writing to a virtual address results in writing to two dataspaces at the same time, so that the dataspaces have the same content.

2) As far as i know a thread has to be added to a rm session as a client in order to be able to use it as layout for its virtual address space. Is it possible for a thread to operate on two different rm_sessions at the same time?

Best Regards, David
