Hello,
First off, allow me to say this. Dolphin does not require ssh access, or version 3 php. It can be done with version 2, which is intermediate. I suggest you apply for that, as you will not be accepted for v3. There's only around 30 or 40 accounts with that, out of thousands. I have seen users successfully install it with v2. I'd suggest, if you have any issues after you get v2, to post on the forums, or even search the forums for someone else who's installed it.
