Install Citrix xstools

We're planning to run a few Open-E instances virtual on Citrix Xenserver. Installing seems to work right now but of course without xstools. Since xstools contain extra drivers for better io and network performance we would like to install them...Is there any option to install these drivers or is there going to be a version that contains these drivers... I guess the same question will be applicable for more platforms like for example vmware.

Having Open-E installed within two vm's on different hosts gives us the possibility to share the local storage of these hosts with other hosts...using iscsi failover and replication we should be able to HA this as well...
