Neil,
        As you know LSP is a technology independent term used in 
MPLS and GMPLS.  The original question (requirement for bidirectional 
asymmetric-bandwidth *TE* LSPs) was intended to identify which 
network modes the WG considered important.  The motivation for the 
question was the discussions on  bidirectional asymmetric-bandwidth 
TE LSPs for co-ps, specifically Ethernet/PBB-TE, see 
draft-takacs-asym-bw-lsp.  Some have asked if we should define a 
mechanisms that supports other co-ps and co-cs technologies.  Others 
have said that we should not define mechanisms for any technology.

Does this help clarify the question?

and I'd claim that the current definition of mp2p is cl-ps...
