Sure. We have studied the effect of the added delay (and jitter) on different services: VoIP, games. We have even used subjective quality estimators in order to see the degradation as a function of the period.
We can include some ideas in the second draft (Delay Limits and Multiplexing Policies to be employed with Tunneling Compressed Multiplexed Traffic Flows, http://datatracker.ietf.org/doc/draft-suznjevic-tsvwg-mtd-tcmtf/ Thanks, Jose PS: A paper about the effect on VoIP: Jose Saldana, Julian Fernandez-Navajas, Jose Ruiz-Mas, Jenifer Murillo, Eduardo Viruete, Jose I.
