It's been a while since I tried to do something like this but IIRC
an IPC-Gate Capability is automatically downgraded when you put it into
a namespace. I.e. cal_server:svr() will not work and instead but the
client side of the IPC-gate into the namespace.

Whether this is intential or not, I don't know.
