Yes!
Ok, I do a reasonable amount of orch related music, but my main reason for VE PRO 5 (and now 6) was to distribute both RAM and CPU load. So my typical set up at the moment looks like this.
DAW PC
Slave 1 orch
Slave 2 choir and FX
Slave 3 VI instruments
For slave 3 I use it for really CPU intensive stuff - like VI moddeling synths, Iris 2, Omni and others. For slave 2 I run the huge convolution reverb Altiverb 7. I route a load of audio through this.
The overall advantage are two fold for me. 1) My Pro tools rig runs like a dream with no stress at all. 2) I have virtual racks of FX and synths just reading to be 'on tap' for any project I am working on. The funny thing is I now run a powerful 64 MB windows 10 system for my DAW and probably many of my projects could be created from within this alone (I do use lots of hardware synths too). But since getting into VE PRO I like the distributed way of working.

p.s. my number one wish for VE PRO is that they finally sort out mono channels. I really was hoping this would be sorted for VE PRO 6. For example, I run BFD 3 (drums) from a slave. It runs really well and takes a whole load off the DAW - but I wish I could simply route the kick mic through a mono channel in VE PRO 6
