RE: [cdt-dev] About default debuggers, etc 
A lot of the TCF info (e.g. http://wiki.eclipse.org/DSDP/TM/TCF_FAQ) is about a TCF agent on target and about the communication between the host and target, the reference implementation was a target agent.  If we only have TCF on host aren't we missing TCF benefits like auto-discovery, tunneling via other targets, etc. maybe Felix B. can give us some light.
