OpenDC Hub - searching in linked hubs?

[hamlet]

Is this feature really working?
I have two linked hubs (same link_pass).
Yes, the search packet goes to the linked hub.
(I'd checked it with a sub multi_hub_data_chunk_in(string data)),
but there seems to be no reaction from the linked hub.
Does it just throw the packet to /dev/null?
Thanx
