			*Sean McKee described his efforts to build a cheap box that would give him a GB per second transfers, disk to disk.
			**They've got a boxes with 10Gb links at UM and CERN that they're working with. But various people are working with them.
			**Micah talked about the possibility of putting other data movers (e.g. bbcp) in side IBP. L-store uses the lower levels of the IBP interface and therefore might be able to do this.
			**From the PoV of the LHC computing model, the depots are buffers. They're looking for a host that could serve as a data pump.
			**Mentioned the possibility of using Clyde to test
			**Fermi can saturate a 10G link, but they have a couple hundred nodes on each end.
			**Question of what we can do at SC with this is still open. We want to try to start testing this combination of technologies soon.
			** UM team will be moving to the Tier2 center soon.

			***The metadata server is ready to go.

	**Clyde		**Clyde
	**??		***This will be the test harness, based on a Blackboard system. The new version is much more generic.
			**SRM interface
			***It's been completed and shown to be interoperable.
			***The client is on the L-store wiki page. They LBL people have used it to move data from Vandy to CERN. They're using their SRM tester on top of L-Store.
			*** Micah wants to set up a persistent SRM/L-Store demo out at ORNL. It would show movement of data via this system back and forth to CERN. Micah will take point on getting this going.
			***Ian Fisk is very excited about this interface, but there SRM version problems.

	**StoreCore		**StoreCore
			***Have a new version up an running with all the dead depots from the old depots removed.
			***They're moving ahead with advanced IBP clients (reader/writer) using Java. They want a new client version ready for demo.
	**LoDN_Brazil (http://dvnserver.pop-sp.rnp.br)		**LoDN_Brazil (http://dvnserver.pop-sp.rnp.br)
	* ~~Anything new~~ on ~~ROOT?~~		***The storage working group is up for review. They're going to show their version of LoDN. It can use either the L-Bone or StoreCore for resource discovery. The integration is done in the WebStart client. There can be user defined volumes added to the store core. This allows people to share a common IBP infrastructure but can also contribute their own. The model they're presenting is a public resource that RNP controls, but which you can add to, but you can also add resources that only.
			***Micah made a point about the problems that we need to watch for with regard to how the different versions of LoDN are evolving manage policy and what that means when you give an exnode to a directory. Hunter's group is doing things like adding group access policy, etc. Need to choose a simple permission structure that people can standardize on.
