No, currently it can't be done within XORP, but we should add
support for this. I just created a bugzilla entry so you can add
yourself to the CC list and get notified when it is implemented:

http://www.xorp.org/bugzilla/show_bug.cgi?id=695

Currently, the only mechanism that comes to mind is using firewall
rules (outside XORP) to allow (or block) the IGMPv3 Membership
Report messages from a specific set of hosts.

Note that such filtering can be applied only to IGMPv3/MLDv2, because
in IGMPv1,v2 and MLDv1 the hosts use Membership Report suppression.
