Is anybody using the ISCSI replication between 2 DSS servers, with ESX 3.01 ?

We currently have running :-

2 DSS servers (Dell 2900)'s with 900 Ggig of storage on each for VMDK's (VMFS)

1 DSS server (Supermicro), that will eventually be used to be the destination for the ISCSI replication (ONCE replication from multiple sources to a single destination is supported)

2 Dell 6850's running ESX 3.01, running the VM's. ESX servers boot from DAS, VM's boot from ISCSI on the DSS boxes.

This is currently working in production, but i was wondering if anyone has statred to use the ISCSI replication, with VMware and is it working for them. IE failover, having both the source and destination Luns visible in ESX ??

Thanks all
