I think FXTeleport is a great product and I hope it works for the folks who are considering it for the new VSL VI's.
One word of caution from a prevous user, though: there is a problem with the software that causes crackles and pops to start to occur and become worse as you continue to work. For me, I think it generally started after about an hour or so then continued to get worse until I had to shut everything down and restart after 90 minutes or a couple of hours (going on memory here, but that seems about right). This problem has been acknowledged by a number of other users, as well. Basically you have to continually increase the network latency setting until the software becomes unusable. Then the standard programmer's fix: reboot.
I bought FXTeleport and was hoping that it would save me the expense of another sound card/MIDI interface and because I was using Halion 2 as a sampler (which won't run standalone - it needs a VST host). But stopping every couple of hours to re-load everything became very tedious (I never saw any updates that addressed the problem) so when Hal3 came along with standalone capability, I got it and another sound card and haven't used FXTeleport since. There used to be a bunch of discussion about it on the FX-Max forum and the Halion forum but both have been "reset" since those days so the posts aren't there anymore.
As I said, I hope it works but I had no luck over many months trying to run sampling VST's. It seems to work fine for FX VST's (hence the name?).
So, I STRONGLY recommend that you get the demo version and try it out (if there is still a demo). The problem is that you can't "try out" the VSL instrument, so it's a tricky situation...
Caveat emptor.
