Vienna Ensemble Pro by VSL
Despite the name and brand, it’s not specifically for orchestral libraries
It lets you host any VST on another pc.
Afaik FXT is x32 only, and dead, no sign from the dev since years.
VEPro 5 supports audio to AND from a DAW, automation, x32<->x64, Mac<->PC, actively supported…
I’ve had a play with fx teleport with 10/100 lan cards it is very limited. It really needs to be run over a gigabit network. In the end I didn’t buy it. I just used the freeze function until I got both a faster machine and a UAD card. I also experimented running vsti’s on a separate machine loaded with Reaper as the host connected via good old fashoined midi and audio cables. It just meant saving the project on both machines. Once I had the latency compensation worked out it was fine. There are also some midi over lan applications such as rtpmidi http://www.tobias-erichsen.de/Software.html
Digital Connection = digital Sync needed + No Automation possible + fixed routing (device wise) = no (semi) automatic workload balance
