If you want to play Russian roulette, you have to accept the risks.
Root.fpj does not autoheal so no surprises there. You can manually recreate it.
I have run some projects over a network using Rh10. I experienced no problems other than the latency of the network. It is not going to be as quick as when the project is local. How much of a difference you will see is directly down to your network so no one can advise you on that. You need to download the trial to a non production machine.
If found the speed loss was not a major problem, most noticeable when generating projects with a few thousand files. No corruption occurred but with anything like this, your mileage may vary.
Running a project that was on an external USB 2 drive connected to my main machine which was then shared and accessed from a virtual machine worked but that was a bit slow, however that is a bit of an extreme test and at least it worked.

Thanks for your fast reply Peter,
I've read about the Russian roulette before in this forum Problem is that this is the environment that was set up and that we have to deal with now. We were not aware of these issues until recently so, yes, it's really our own fault.
How can we manually recreate root.fpj?
Regarding the problems with speed loss on networks, I can't imagine RH10 being even slower than RH9 is now on our network, so this doesn't worry me.
