The way I have implemented labelspaces allows for more flexibility then the
standard notions of "interface" or "platform".

You can add as many interfaces to any labelspace.  The result is that every
label added to that labelspace is availble on every interface assigned to
that labelspace.

(one thing to remember is that typically the platform (or global) labelspacer
is designated by labelspace 0)

If your wondering about how "application" labels (the labels below to top
label in the stack) fit into this scheme, explain the particular application
and I'll be more then happy to explain how mpls-linux can support it.

The notion of label range is configured and enforced by the signaling plane
not the forwarding plane.

Look at iptables (and the iptables patch included in the mpls-linux
distribution)
